Question

I have been Following this tutorial https://learn.microsoft.com/en-us/outlook/rest/python-tutorial , but unfortunately ran into an error
i.e. KeyError : access_token
Below is the traceback :

Internal Server Error: /tutorial/gettoken/  
Traceback (most recent call last):  
  File "C:\Users\lenovo\Desktop\myapi\v\lib\site-packages\django\core\handlers\exception.py", line 34, in inner  
    response = get_response(request)  
  File "C:\Users\lenovo\Desktop\myapi\v\lib\site-packages\django\core\handlers\base.py", line 115, in _get_response  
    response = self.process_exception_by_middleware(e, request)

  File "C:\Users\lenovo\Desktop\myapi\python_tutorial\tutorial\views.py", line 17, in gettoken  
    access_token = token['access_token']

I have cross verified each and every step of the my code and there seems no mismatch even in AAD it is same as in tutorial. and facing this issue since last night . can anyone help me out?

Answer 1

@akash verma I tracked the correlation ID in our backend database and found that Redirect URI in Request is 'http://localhost/tutorial/gettoken' and Configured on the app is 'http://localhost/tutorial/gettoken/'.

Please remove the trailing slash from everywhere (your code and app registered in AAD) and then try again.

I made mistake of adding client secret ID instead value, after replacing it got resolved.
