I get this error when I send a message to the bot in Teams File "/tmp/8dc2d85e57d1267/antenv/lib/python3.9/site-packages/botframework/connector/auth/microsoft_app_credentials.py", line 65, in get_access_token 2024-02-15T18:46:14.580265935Z return auth_token["access_token"] 2024-02-15T18:46:14.580271097Z KeyError: 'access_token' 2024-02-15T18:46:14.582736909Z DEBUG:msal.telemetry:Generate or reuse correlation_id: 439bd6b3-d71d-4c04-a9cc-d1e6b6dbcffd 2024-02-15T18:46:14.583496313Z INFO:aiohttp.access:[ip] [15/Feb/2024:18:46:14 +0000] "POST /api/messages HTTP/1.1" 404 172 "-" "Microsoft-SkypeBotApi (Microsoft-BotFramework/3.0)" The app id and password are correct, how can I resolve this?

Based on the error message you provided, it seems that there is an issue with retrieving the access token from the Microsoft App Credentials in your Python code. The error specifically mentions a KeyError for 'access_token'.

To resolve this issue, you can try the following steps:

Make sure you have correctly set up the Microsoft App Credentials with the correct app ID and password. Double-check that the values you are using in your code match the values in the Azure portal.

Ensure that you have the necessary permissions and scopes configured for your bot in the Azure portal. The bot needs the appropriate permissions to access the required resources.

Verify that you are using the correct endpoint URL for sending messages to the bot. The error message shows a 404 response, which indicates that the endpoint URL might be incorrect or the bot is not properly registered.

Check if you have properly initialized the Microsoft App Credentials in your Python code. Make sure you are using the correct credentials object and passing it to the appropriate API calls.

I'm having the same problem. It appeared since botbuilder-integration-aiohttp==4.15.0.

If I do like this:

from botframework.connector.auth import MicrosoftAppCredentials

creds = MicrosoftAppCredentials(CONFIG.APP_ID, CONFIG.APP_PASSWORD)
access_token = creds.get_access_token()

and then send a message to the bot

r = requests.post(BOT_ENDPOINT, json=data, headers={"Authorization": f"Bearer {access_token}"})

The bot will fail with:
File "/Users/blabla/python3.10/site-packages/botframework/connector/auth/app_credentials.py", line 92, in signed_session auth_token = self.get_access_token() File "/Users/blabla/python3.10/site-packages/botframework/connector/auth/microsoft_app_credentials.py", line 54, in get_access_token return auth_token["access_token"] KeyError: 'access_token' WARNING:root:Request <Request POST /api/messages > has failed with exception: KeyError('access_token')

for 4.14.8 and below - it works fine

Ensure that all dependencies, including the botframework library and its dependencies, are up to date.
Also try getting acccess token using the appCredentials.GetTokenAsync() method
