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 ?
