Starting from 4.15.0 - <Request POST /api/messages > has failed with exception: KeyError('access_token')

Version

4.15.0

Describe the bug

Starting from 4.15.0 version, when using MicrosoftAppCredentials(CONFIG.APP_ID, CONFIG.APP_PASSWORD).get_access_token() to send request to bot - now fails with <Request POST /api/messages > has failed with exception: KeyError('access_token').

In 4.14.8 and below - it works fine.

To Reproduce

Steps to reproduce the behavior:

1. Start bot locally
2. Get token and send POST request to the bot

   
   import requests
   from botframework.connector.auth import MicrosoftAppCredentials

from config import CONFIG

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

BOT_ENDPOINT = f"http://0.0.0.0:{CONFIG.PORT}/api/messages" requests.post(BOT_ENDPOINT, json=data, headers={"Authorization": f"Bearer {access_token}"})

3. See bot logs

## Expected behavior
The request is received by the bot without any errors, as it was in 4.14.8 and below, without token issue

Any update on this? This is exactly the error I am seeing on my infrastructure. However I have the same error regardless of the version. Checked 4.15.0, previous 4.14.8 and also 4.14.7.

[elabbarw]

I am getting this as well. Falling back to 4.14.8 didn't fix it.

I am also getting the same issue
