When using Oauth2 generic connector, AADSTS90014: The request body must contain the following parameter: 'client_id'

When using Oauth2 generic connector, we encounter the following error :

AADSTS90014: The request body must contain the following parameter: 'client_id'


The following screenshots show the way we are configuring the custom connector and the error message we are getting.

As it works with postman, I added one more screenshot of postman's configuration panel to get token.


Are we missing something, or is it a bug of the powerapps custom connector configuration wizard ? 




Hey @quentin-roger 


Can you try to follow below steps and check if the issue gets resolved.
1) Save the Postman request to a collection.
2) Export this collection in v1 format.
3) Import this as a custom connection on powerapps.
4) Check if all the steps are configured properly.
5) Now, try to create a connection.
Hope this Helps!
