Bot token is not refreshed after an hour and a 401 is received upon ctx.send

[octopus-eran]

The simple echo server is reading the CLIENT_SECRET, TENANT_ID and CLIENT_ID and is able to generate the graph and bot tokens.
After one hour, the graph token is refreshed but the bot token is not, and therefore the ctx.send call to reply to user's message is falling with 401 unauthorized exception.

@octopus-eran any logs you can share with us? Thank you for reporting!

[octopus-eran]

@heyitsaamir Thanks for being prompt! My code is pretty much the simple example of the "echo" template, with a token_factory so I can track when the get_token is called by the SDK.

Here it is:

import os
import time
import asyncio
import re
import requests
from typing import Any, Optional, Tuple

from azure.identity import ClientSecretCredential
from azure.core.credentials import AccessToken
from microsoft.teams.api import (
    MessageActivity,
    TypingActivityInput,
    InstalledActivity,
    MessageActivityInput,
)

from microsoft.teams.apps import ActivityContext, App
from microsoft.teams.devtools import DevToolsPlugin

TENANT_ID = os.environ["TENANT_ID"]
CLIENT_ID = os.environ["CLIENT_ID"]
CLIENT_SECRET = os.environ["MY_CLIENT_SECRET"]


TOKEN_URL = f"https://login.microsoftonline.com/{TENANT_ID}/oauth2/v2.0/token"


def create_token_factory():

    def get_token(scopes, tenant_id=None) -> str:
        # Normalize scopes arg; SDK may pass a string or tuple
        if isinstance(scopes, str):
            scopes = [scopes]
        scopes = list(scopes)

        # Decide the resource from scopes (one resource per client_credentials token)
        if any("graph.microsoft.com" in s for s in scopes):
            resource = "https://graph.microsoft.com"
        else:
            resource = "https://api.botframework.com"

        form = {
            "grant_type": "client_credentials",
            "client_id": CLIENT_ID,
            "client_secret": CLIENT_SECRET,
            "scope": f"{resource}/.default",  # <-- GRAPH: https://graph.microsoft.com/.default
        }
        print(f"[cred] requesting token for {resource} at {TOKEN_URL}")
        r = requests.post(TOKEN_URL, data=form, timeout=15)
        print(f"[cred] AAD status={r.status_code}")
        r.raise_for_status()
        js = r.json()
        tok = js["access_token"]
        return tok  # return STRING, not AccessToken

    return get_token


app = App(token=create_token_factory())


@app.on_message_pattern(re.compile(r"hello|hi|greetings"))
async def handle_greeting(ctx: ActivityContext[MessageActivity]) -> None:
    await ctx.send("Hello! How can I assist you today?")


@app.on_message
async def handle_message(ctx: ActivityContext[MessageActivity]):
    await ctx.reply(TypingActivityInput())
    await ctx.send(f"You said '{ctx.activity.text}'")


def main():
    asyncio.run(app.start())


if __name__ == "__main__":
    main()

Here is the console when I start the app and send the first message from teams, as you can see, both graph and bot tokens are requested and successfully generated:

Later, after one hour+, I try to send another message from teams, and now I get the graph token refreshed but with the 401 error:

Again, thanks for replying and for this great package!

Hi @heyitsaamir, I'm following the PR and have a question. I see that you manage both the Bot and Graph tokens and although one bot token can be used to reply to multiple tenants, the Graph token needs to be issued per tenant (per customer of mine), is there an option to issue the graph token myself, persist it per customer and inject it to the SDK when needed?

Hi @heyitsaamir, Thanks a lot. I also encountered this error last week and have been struggling with a workaround since then.
Very appreciate the help.
