What causes Google Sheets API Traceback/Refresh Error? - python

Hi I am high school senior and I want to do a small program for a school project.
I need to get information from a google sheet into my code. I followed this guide to try to do this. I followed every step and put in all my info properly, but I keep getting this error.
Traceback (most recent call last):

This is my code for reference:
import gspread
from oauth2client.service_account import ServiceAccountCredentials
from pprint import pprint
scope = ["https://spreadsheets.google.com/feeds",'https://www.googleapis.com/auth/spreadsheets',"https://www.googleapis.com/auth/drive.file","https://www.googleapis.com/auth/drive"]
creds = ServiceAccountCredentials.from_json_keyfile_name("TPOL2.json", scope)
client = gspread.authorize(creds)
sheet = client.open("tpol2").sheet1 # Open the spreadhseet
data = sheet.get_all_records() # Get a list of all records
print(data)
I can run each line except the last 3 which leads me to believe the code is able to get online properly, but there is something in the way between the code and the google sheet.
Any help would very much appreciated.

ok i found solution
Actually i was running this code from android mobile IDE
and in my google sheet setting transfer files only over wi-fi was enabled. And i havent connected to wifi using net through sim card.
So I think bot was trying to transfer data but wifi setting not allowing it so time out error was generated.
Now i changed the setting and code is running smoothly

401 HTTP Response, when I load client secret and client-ID from praw.ini

Recently, I started a PRAW project aiming to scrape from the r/todayilearned subreddit. Browsing through the docs, if found that the best way to load up the client-id, client secret, username, and password was to store it in the praw.ini file.
This is the format I used where the ".........." were filled by the respective inputs.
[TIL]
client_id="´............"
client_secret="............"
password="............"
username=".........."
user_agent="TIL by u/........"
I executed this code and I get

How can I fix this?
Thanks in Advance.
I tested it and it has to be without " "

client_secret=Bq7............X0z
password=SeCrEtPaSsWoRd

but it can use spaces to make it more readable
[TIL]
client_id = 2Ca......Mh4
client_secret = Bq7............X0z
password = SeCrEtPaSsWoRd
username = james_bond
user_agent = TIL by u/james_bond
BTW:
It may also use : instead of =
[TIL]
client_id:2Ca......Mh4
client_secret:Bq7............X0z
password:SeCrEtPaSsWoRd
username:james_bond
user_agent:TIL by u/james_bond
[TIL]
client_id : 2Ca......Mh4
client_secret : Bq7............X0z

user_agent : TIL by u/james_bond
EDIT:
I checked documentation praw.ini Files and it shows examples also without " "

Firestore client in python (as user) using firebase_admin or google.cloud.firestore

I am building a python client-side application that uses Firestore. I have successfully used Google Identity Platform to sign up and sign in to the Firebase project, and created a working Firestore client using google.cloud.firestore.Client which is authenticated as a user:
import json
import requests
import google.oauth2.credentials
from google.cloud import firestore
request_url = f"https://identitytoolkit.googleapis.com/v1/accounts:signInWithPassword?key={self.__api_key}"
headers = {"Content-Type": "application/json; charset=UTF-8"}
data = json.dumps({"email": self.__email, "password": self.__password, "returnSecureToken": True})
response = requests.post(request_url, headers=headers, data=data)
try:
response.raise_for_status()
except (HTTPError, Exception):
content = response.json()
error = f"error: {content['error']['message']}"
raise AuthError(error)
json_response = response.json()
self.__token = json_response["idToken"]
self.__refresh_token = json_response["refreshToken"]
credentials = google.oauth2.credentials.Credentials(self.__token,
self.__refresh_token,
client_id="",
client_secret="",
token_uri=f"https://securetoken.googleapis.com/v1/token?key={self.__api_key}"
)
self.__db = firestore.Client(self.__project_id, credentials)
I have the problem, however, that when the token has expired, I get the following error:

google.api_core.exceptions.Unauthenticated: 401 Missing or invalid authentication.
I have tried omitting the token and only specifying the refresh token, and then calling credentials.refresh(), but the expires_in in the response from the https://securetoken.googleapis.com/v1/token endpoint is a string instead of a number (docs here), which makes _parse_expiry(response_data) in google.oauth2._client.py:257 raise an exception.
Is there any way to use the firestore.Client from either google.cloud or firebase_admin and have it automatically handle refreshing tokens, or do I need to switch to the manually calling the Firestore RPC API and refreshing tokens at the correct time?
Note: There are no users interacting with the python app, so the solution must not require user interaction.
Can't you just pass the string cast as integer _parse_expiry(int(float(response_data))) ?
If it is not working you could try to make a call and refresh token after getting and error 401, see my answer for the general idea on how to handle tokens.
As mentioned by #Marco, it is recommended that you use a service account if it's going to be used in an environment without user. When you use service account, you can just set GOOGLE_APPLICATION_CREDENTIALS environment variable to location of service account json file and just instantiate the firestore Client without any credentials (The credentials will be picked up automatically):
import firestore
client = firestore.Client()
and run it as (assuming Linux):
$ export GOOGLE_APPLICATION_CREDENTIALS=/path/to/credentials.json
$ python file.py
Still, if you really want to use user credentials for the script, you can install the Google Cloud SDK, then:
$ gcloud auth application-default login
This will open browser and for you to select account and login. After logging in, it creates a "virtual" service account file corresponding to your user account (that will also be loaded automatically by clients). Here too, you don't need to pass any parameters to your client.

Accessing google cloud storage bucket from cloud functions throws 500 error

I'm trying to access google cloud storage bucket from cloud functions (python) instance and it's throwing mystic 500 error.
I have given the service account editor role too. It didn't make any change.
I also checked if any of the quota is going off limit. The limits were not even close.
Please, anyone can help me find cause of this error?
here is the code
from google.cloud import storage
import os
import base64
storage_client = storage.Client()
def init_analysis(event, context):
print("event", event)
pubsub_message = base64.b64decode(event['data']).decode('utf-8')
print(pubsub_message)
bucket_name = 'my-bucket'
bucket = storage_client.get_bucket(bucket_name)
blobs = bucket.list_blobs()
for blob in blobs:
print(blob.name)

The error you are getting it's because your Cloud Functions service account doesn't have the cloudfunctions.serviceAgent role. As you can see on the documentation:
Authenticating as the runtime service account from inside your function may fail if you change the Cloud Functions service account's permissions.
However, I found that sometimes you can not add this role as it doesn't show up as an option. I have reported this issue to the Google Cloud Functions engineering team and they are working to solve it.
Nevertheless, you can add the role again using this gcloud command:
gcloud projects add-iam-policy-binding <project_name> --role=roles/cloudfunctions.serviceAgent --member=serviceAccount:service-<project_number>#gcf-admin-robot.iam.gserviceaccount.com

Double check your credentials as this note says.
Remember that the username is your reddit's account name, not the bot's name.
Another possibility is your bot has been timed out for too many login attempts.
An easy way to check this by trying to log into Reddit manually and checking if you're blocked.
You might be using two-factor authentication with this account.
You have to disable it, or pass the 2FA code with the password in one stiring separated by a colon, like this:
r = praw.Reddit(user_agent = "test bot",
username = config.username,
password = f"{config.password}:{2FA-Code}",
client_id = config.client_id,
client_secret = config.client_secret)
See this in the docs:
