OAuth2 client error

[Sebastien_REGNO]

Hi,

When trying to connect AppSheet to my organization's own OIDC provider (OAuth 2.1 compliant), AppSheet returns the following error after redirection :

{"error": "invalid_client", "error_description": "Wrong authentication method used, MUST use 'client_secret_basic'"}

Does AppSheet try to use another authentication method ?
Is there a way to have AppSheet use client_secret_basic instead ?

Thanx in advance for your help,

Sebastien

If you can't find an answer in the help docs:

https://help.appsheet.com/en/?q=oauth2

I suggest engaging Support:

We finally found that the error was returned by our OAuth application and it was not AppSheet that was showing this message.

Perhaps some explanation would help ? Ex : "Message returned from the server : ...."
