I'm watching the tutorial of freeCodeCamp.org,
Solidity, Blockchain, and Smart Contract Course – Beginner to Expert Python Tutorial (link of the video course) and I'm stucked at 04:06:47 because when I try to build a transaction and sign it, my compiler gives me back a lot of errors:

I first searched on internet for solutions, but the only one was to add in the transation build one more parameter (the one of the gasPrice), but it didn't solve my problems.
I hope someone can help me, here is the full code I wrote:
from solcx import compile_standard, install_solc
import json
from web3 import Web3
from dotenv import load_dotenv
import os
load_dotenv()
install_solc("0.6.0")
with open("./simpleStorage.sol", "r") as file:
simple_storage_file = file.read()
compiled_sol = compile_standard(
{
"language": "Solidity",
"sources": {"simpleStorage.sol": {"content": simple_storage_file}},
"settings": {
"outputSelection": {
"*": {"*": ["abi", "metadata", "evm.bytecode", "evm.sourceMap"]}
}
},
},
solc_version="0.6.0",
)
with open("compiledCode.json", "w") as file:
json.dump(compiled_sol, file)
bytecode = compiled_sol["contracts"]["simpleStorage.sol"]["SimpleStorage"]["evm"][
"bytecode"
]["object"]
abi = compiled_sol["contracts"]["simpleStorage.sol"]["SimpleStorage"]["abi"]
w3 = Web3(Web3.HTTPProvider("HTTP://127.0.0.1:7545"))
chain_id = 5777
my_address = "0xd8BADAe3766759e7e298931dF01F452616dc6dde"
pvt_key = os.getenv("PRIVATE_KEY")
SimpleStorage = w3.eth.contract(abi=abi, bytecode=bytecode)
nonce = w3.eth.getTransactionCount(my_address)
transaction = SimpleStorage.constructor().buildTransaction(
{
"chainId": chain_id,
"gasPrice": w3.eth.gas_price,
"from": my_address,
"nonce": nonce,
},
)
signed_txn = w3.eth.sign_transaction(transaction, private_key=pvt_key)
Try changing your chain_id = 5777 to chain_id = 1337.
If you are using ganache quickstart, instead use New Workspace option so you can save it.
Go to settings on top right corner (If you are using GUI from tutorial video)
Go to server tab and select following values and save.
Change values accordingly in your code.
Also change create trasaction code to this
transaction = SimpleStorage.constructor().buildTransaction(
{
"chainId": chain_id,
"gasPrice": w3.eth.gas_price,
"from": my_address,
"nonce": nonce,
}
)
Doing these 2 steps should fix your problem. I just did it for myself.

I am following that popular solidity course in which a lot of people encoutered the web3 gas_price problem.
Below is the original script that everyone here must be familiar.
from solcx import compile_standard, install_solc
import json
from web3 import Web3
with open("./SimpleStorage.sol", "r") as file:
simple_storage_file = file.read()
install_solc("0.6.0")
compiled_sol = compile_standard(
{
"language": "Solidity",
"sources": {"SimpleStorage.sol": {"content": simple_storage_file}},
"settings": {
"outputSelection": {
"*": {"*": ["abi", "metadata", "evm.bytecode", "evm.sourceMap"]}
}
},
},
solc_version="0.6.0",
)
with open("compiled_code.json", "w") as file:
json.dump(compiled_sol, file)
# Get bytecode
bytecode = compiled_sol["contracts"]["SimpleStorage.sol"]["SimpleStorage"]["evm"][
"bytecode"
]["object"]
# Get ABI
abi = compiled_sol["contracts"]["SimpleStorage.sol"]["SimpleStorage"]["abi"]
# for connecting to ganache
w3 = Web3(Web3.HTTPProvider("http://127.0.0.1:7545"))
chain_id = 1337
my_address = "0xa217118d0C418048007B2f935489880F98650cC7"
private_key = "0x8a1e2a2b30b6a8886ba6dd1738af9d30237fd7e286f886495ae3528279f70f6b"
# Create the contract in python
SimpleStorage = w3.eth.contract(abi=abi, bytecode=bytecode)
print(SimpleStorage)
# Get the latest transaction
nonce = w3.eth.getTransactionCount(my_address)
print(nonce)
# 1. Build a transaction
# 2. Sign a transaction
# 3. Send a transaciton
transaction = SimpleStorage.constructor().buildTransaction(
{
"gasprice": w3.eth.gas_price,
"chainId": chain_id,
"from": my_address,
"nonce": nonce,
}
)
print(transaction)
I had tried
transaction = SimpleStorage.constructor().buildTransaction(
{
"gasprice": w3.eth.gas_price,
"chainId": chain_id,
"from": my_address,
"nonce": nonce,
}
)
But I still get this error

Its seems adding the code "gas_price" doesn't work in my case. Any suggestions about what I went wrong please?
Solution found. The price of "gasprice" needs to be a capital.
transaction = SimpleStorage.constructor().buildTransaction(
{
"gasPrice": w3.eth.gas_price,
"chainId": chain_id,
"from": my_address,
"nonce": nonce,
}
)
I am trying to deploy my SimpleStorage.sol contract to a ganache local chain by making a transaction using python. It seems to have trouble connecting to the chain.
from solcx import compile_standard
from web3 import Web3
import json
import os
from dotenv import load_dotenv
load_dotenv()
with open("./SimpleStorage.sol", "r") as file:
simple_storage_file = file.read()
compiled_sol = compile_standard(

"sources": {"SimpleStorage.sol": {"content": simple_storage_file}},
"settings": {
"outputSelection": {
"*": {"*": ["abi", "metadata", "evm.bytecode", "evm.sourceMap"]}
}
},
},
solc_version="0.6.0",
)
with open("compiled_code.json", "w") as file:
json.dump(compiled_sol, file)
# get bytecode
bytecode = compiled_sol["contracts"]["SimpleStorage.sol"]["SimpleStorage"]["evm"][
"bytecode"
]["object"]
# get ABI
abi = compiled_sol["contracts"]["SimpleStorage.sol"]["SimpleStorage"]["abi"]
# to connect to ganache blockchain
w3 = Web3(Web3.HTTPProvider("HTTP://127.0.0.1:7545"))
chain_id = 5777
my_address = "0xca1EA31e644F13E3E36631382686fD471c62267A"
private_key = os.getenv("PRIVATE_KEY")
# create the contract in python
SimpleStorage = w3.eth.contract(abi=abi, bytecode=bytecode)
# get the latest transaction
nonce = w3.eth.getTransactionCount(my_address)
# 1. Build a transaction
# 2. Sign a transaction
# 3. Send a transaction
transaction = SimpleStorage.constructor().buildTransaction(
{"chainId": chain_id, "from": my_address, "nonce": nonce}
)
print(transaction)
It seems to be connected to the ganache chain because it prints the nonce, but when I build and try to print the transaction
here is the entire traceback call I am receiving

Had this issue myself, apparently it's some sort of Ganache CLI error but the simplest fix I could find was to change the network id in Ganache through settings>server to 1337. It restarts the session so you'd then need to change the address and private key variable.
If it's the same tutorial I'm doing, you're likely to come unstuck after this... the code for transaction should be:
transaction =
SimpleStorage.constructor().buildTransaction( {
"gasPrice": w3.eth.gas_price,
"chainId": chain_id,
"from": my_address,
"nonce": nonce,
})
print(transaction)
Otherwise you get a value error if you don't set the gasPrice
this line of code is wrong
chain_id = 5777
Ganache chain id is not 5777. This is network id. Network id is used by nodes to transfer data between nodes that are on the same network. Network id is not included in blocks and it is not used for signing transactions or mining blocks.
chain_id = 1377
Chain ID is not included in blocks either, but it is used during the transaction signing and verification process.
It works for me, I get value chain_id from w3.eth.chain_id
transaction = SimpleStorage.constructor().buildTransaction(
{
"gasPrice": w3.eth.gas_price,
"chainId": w3.eth.chain_id,
"from": my_address,
"nonce": nonce,
}
)
Delegates to eth_chainId RPC Method
Returns an integer value for the currently configured “Chain Id” value introduced in EIP-155. Returns None if no Chain Id is available.
Hey it happened to me too, you need to build the constructor like this
SimpleStorage.constructor().buildTransaction( {
"gasPrice": w3.eth.gas_price,
"chainId": chain_id,
"from": my_address,
"nonce": nonce,
You need to add the gas price part.
Worked for me
I encountered this issue today and after debugging, I am certain that the issue is from the dotenv config variables imported. All the variables are been seen by python as strings, and for some reason, the web3 library swaps the value 5777 if the type of your chain id is not an integer.
The perfect fix is to cast your chain_id into type int before deploying your smart contract.
Hope this saves y'all some pondering time, peace out!
Snippet example below:
transaction = SimpleStorage.constructor().buildTransaction(
{
"gasPrice": w3.eth.gas_price,
"chainId": int(chain_id),
"from": my_address,
"nonce": nonce,
}
)
Perhaps, you are following FreeCodeCamp tutorial.
I have got the same problem
In my case, it is working after adding gas price, "gasPrice": w3.eth.gas_price
transaction = SimpleStorage.constructor().buildTransaction({ "gasPrice": w3.eth.gas_price, "chainId" : chain_id, "from": my_address, "nonce": nonce})
print(transaction)
You can check your chainId using the following code
const chainId = await wallet.getChainId();
console.log("chain Id",chainId);
For me it was 1337
I have a query that joins on a jsonb type column in postgres that I want to convert to sqlalchemy in django using the aldjemy package
SELECT anon_1.key AS tag, count(anon_1.value ->> 'polarity') AS count_1, anon_1.value ->> 'polarity' AS anon_2
FROM feedback f
JOIN tagging t ON t.feedback_id = f.id
JOIN jsonb_each(t.json_content -> 'entityMap') AS anon_3 ON true
JOIN jsonb_each(((anon_3.value -> 'data') - 'selectionState') - 'segment') AS anon_1 ON true
where f.id = 2
GROUP BY anon_1.value ->> 'polarity', anon_1.key;
The json_content field stores data in the following format:
{
"entityMap":
{
"0":
{
"data":
{
"people":
{
"labelId": 5,
"polarity": "positive"
},
"segment": "a small segment",
"selectionState":
{
"focusKey": "9xrre",
"hasFocus": true,
"anchorKey": "9xrre",
"isBackward": false,
"focusOffset": 75,
"anchorOffset": 3
}
},
"type": "TAG",
"mutability": "IMMUTABLE"
},
"1":
{
"data":
{
"product":
{
"labelId": 6,
"polarity": "positive"
},
"segment": "another segment",
"selectionState":
{
"focusKey": "9xrre",
"hasFocus": true,
"anchorKey": "9xrre",
"isBackward": false,
"focusOffset": 138,
"anchorOffset": 79
}
},
"type": "TAG",
"mutability": "IMMUTABLE"
}
}
}
I wrote the following sqlalchemy code to achieve the query
first_alias = aliased(func.jsonb_each(Tagging.sa.json_content["entityMap"]))
print(first_alias)
second_alias = aliased(
func.jsonb_each(
first_alias.c.value.op("->")("data")
.op("-")("selectionState")
.op("-")("segment")
)
)
polarity = second_alias.c.value.op("->>")("polarity")
p_tag = second_alias.c.key
_count = (
Feedback.sa.query()
.join(
CampaignQuestion,
CampaignQuestion.sa.question_id == Feedback.sa.question_id,
isouter=True,
)
.join(Tagging)
.join(first_alias, true())
.join(second_alias, true())
.filter(CampaignQuestion.sa.campaign_id == campaign_id)
.with_entities(p_tag.label("p_tag"), func.count(polarity), polarity)
.group_by(polarity, p_tag)
.all()
)
print(_count)
but it is giving me a NotImplementedError: Operator 'getitem' is not supported on this expression error on accessing first_alias.c

Any help would be greatly appreciated
PS: The sqlalchemy version I'm using for this is 1.4.6
I used the same sqlalchmy query expression before in a flask project using sqlalchemy version 1.3.22 and it was working correctly
Fixed the issue by using table_valued functions as mentioned in the docs,
and accessing the ColumnCollection of the function using indices instead of keys. Code is as follows:
first_alias = func.jsonb_each(Tagging.sa.json_content["entityMap"]).table_valued(
"key", "value"
)
second_alias = func.jsonb_each(
first_alias.c[1].op("->")("data").op("-")("selectionState").op("-")("segment")
).table_valued("key", "value")
polarity = second_alias.c[1].op("->>")("polarity")
p_tag = second_alias.c[0]
I'm trying to upload an image with Django Rest Framework and AWS S3.
settings.py:

models.py:
class Beat(models.Model):
...
image = models.ImageField(upload_to='static/', default = 'static/None/No-img.gif', null = True)
S3 bucket policy:

}
]
}
However, when I upload an image, it gives error:
boto.exception.S3ResponseError: S3ResponseError: 400 Bad Request
I can't figure out what the problem is.
python manage.py collectstatic works well.
How can I fix this error?
Thanks.
