pyrogram: Client produce KeyError while starting the bot

Question

When I am starting my telegram bot by Pyrogram using the latest version v2.0.103

app = Client("BillyKaiChengBot",api_id="apiid",api_hash=os.environ['API'],bot_token=os.environ['TOKEN'])
    
with app: #error produces here
    loginapp = app.send_message(channel_id, "login")

#my own code
#.
#.
#.
app.run()

This code can run smoothly until recently, it produces this error

Traceback (most recent call last):
  File "main.py", line 47, in <module>
    with app:

    return cast(TLObject, objects[int.from_bytes(b.read(4), "little")]).read(b, *args)
KeyError: 0

I tried to reinstall the module but it not works. Any help would be appreciated!

sorry I didnt copy the error code completely. You can see my edit now. — Sorry for my bad English, Apr 19 '23 at 02:18

According to the owner response in GitHub, the main reason of this issue is caused by server or network issue, not from the code or module itself.

The issue is related to empty responses received from the server and is not reproducible consistently. It's very likely just a momentary server or network issue

You are combining 2 ways of calling app.run().

You should use it like so, where you pass a function to run:

app = Client("my_account")

async def main():
    async with app:
        print(await app.get_me())


app.run(main())

OR, if you don't want a main(), you can also do:

app = Client("my_account")

@app.on_message(filters.text & filters.private)
async def echo(client, message):
    await message.reply(message.text)


app.run()  # Automatically start() and idle()

Note that in the second example, there is no with app, that's were your error is coming from. Pick one of those.

Both snippets are part of pyrogram's examples.
