How to fix "hyper.http20.exceptions.ConnectionError: Encountered error FRAME_SIZE_ERROR 0x6: Frame size incorrect" error in python

I have a requirement to send HTTP/2 get and post request to unit test rest api server.
I tried to use request library but it seems that it doesn't support HTTP/2. So I integrated request library along with hyper transport adapter like below:
import requests
from hyper.contrib import HTTP20Adapter
s = requests.Session()
data={
"param1": 3000,
"param2": 10,
"param3": 2,
"param4": "2200",
"param5": "800",
"param6": "2200",
"param7": "2000",
"param8": "1700",
"param9": "1200",
"param10": 60,
"param11": "23:00-22:59",
"param12": 3,
"param13": True,
"param14": 85
}
s.verify="/path to ca-cert file"
s.mount('https://', HTTP20Adapter())
r = s.post('https://localhost:1000/config', data=data)
print(r.status_code)
print(r.url)
But it is throwing error:
Traceback (most recent call last):

hyper.http20.exceptions.ConnectionError: Encountered error FRAME_SIZE_ERROR 0x6: Frame size incorrect
How to fix this issue?
I tried to explore to increase frame size which receiver receives and I got following from this link
To implement one of these objects, you will want to subclass the
BaseFlowControlManager class and implement the increase_window_size()
method. As a simple example, we can implement a very stupid flow
control manager that always resizes the window in response to incoming
data like this:
class StupidFlowControlManager(BaseFlowControlManager):
def increase_window_size(self, frame_size):
return frame_size
The class can then be plugged straight into a connection object:
HTTP20Connection('http2bin.org', window_manager=StupidFlowControlManager)
But I don't know how to make use of this class in my code.

Can't read from a .env file

I'm new to python, and I am trying to build a little Reddit bot to get some practice.
My bot works just fine (tested many times) but once I try to move the credentials to a .env file it fails.
I've ran pip3 install python-dotenv
This is my code, just one file, removing irrelevant stuff:
import os
import praw
import firebase_admin
from firebase_admin import credentials
from firebase_admin import db
from dotenv import load_dotenv
load_dotenv()
cred = credentials.Certificate("serviceAccountKey.json")
firebase_admin.initialize_app(cred, {
'databaseURL': 'https://makideat-6a-default-db.firebaseio.com'
})
db_ref = db.reference()
reddit = praw.Reddit(
client_id=os.getenv('CLIENT_ID'),
client_secret=os.getenv('CLIENT_SECRET'),
username=os.getenv('USERNAME'),
password=os.getenv('PASSWORD'),
user_agent=os.getenv('USER_AGENT')
)
def summoned_reply(comment):
DO SOME STUFF...
messages = reddit.inbox.stream() # creates an iterable for your inbox and streams it
for message in messages: # iterates through your messages
try:
if message in reddit.inbox.mentions() and message in reddit.inbox.unread():
summoned_reply(message)
message.mark_read()
except praw.exceptions.APIException:
print("probably a rate limit....")
And this is the error I'm getting (line 56 is for message in messages:):

Then, in the same directory I have a .env file in the following structure (changed characters for everything here of course, but haven't changed the structure or added or removed spaces from anywhere):
CLIENT_ID=gGATUW-Ea507LoQ
CLIENT_SECRET=_b6vCCHKBCqVHzlJin3sEQ
USERNAME=Maddeeat
PASSWORD=!Neatat!
USER_AGENT=Maddeeat:1.0.0 (by u/Maddeeat)

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

reddit = praw.Reddit("TIL")
subreddit = reddit.subreddit('learnpython')

But, when I do this, It works.

)
subreddit = reddit.subreddit('learnpython')
How can I fix this?
Thanks in Advance.

I tested it and it has to be without " "
[TIL]
client_id=2Ca......Mh4
client_secret=Bq7............X0z
password=SeCrEtPaSsWoRd
username=james_bond
user_agent=TIL by u/james_bond
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
password : SeCrEtPaSsWoRd
username : james_bond
user_agent : TIL by u/james_bond
EDIT:
I checked documentation praw.ini Files and it shows examples also without " "

Best way to use Python and Bit Bucket

I am having problems with Python and Bit Bucket. To display/pull/push do anything really.
I am looking # Two different libs, atlassian-python-api, and stashy, both seem to have problems my code is very simple:
from atlassian import Bitbucket
import getpass
username = input("What is your username: ")
password = getpass.getpass(prompt="Enter your password?: ")
bitbucket = Bitbucket(
url="https://website.com:port/projects/demo_projects/repppos/",
username=username,
password=password)
data = bitbucket.project_list()
both give me this error: using stashy and another library. I heard someone suggest to use Rest API but I have no experience with this?

ValueError: uri must include a scheme and netloc
Anyhelp how to resolve this

From my understanding, this error was caused by:
normalized_uri = signature.base_string_uri(uri, headers.get('Host', None))
In this code, uri is None, so it will use Host in headers:
headers.get('Host', None)
However, a Host in headers will contain no schema, a Host looks like:
www.google.com
No https:// in Host. You may need to report a bug to the library.
There is another library (I'm the author), which shares a familiar API with requests-oauthlib, you can check: https://docs.authlib.org/en/latest/client/oauth1.html
from authlib.integrations.requests_client import OAuth1Session
