Invalid Authorization Code error using OAuth 2.0 policy PKCE Flow

[yahyaoui]

Hello,

I'm having issue with configuring OAuth 2.0 with the default policy OAuthV2.

The PKCE Flow was up and running since today I get
{"error":"invalid_grant","error_description":"Invalid authorization code"}

Here is an example of the request(payload) sent

code=wUWZClnU&grant_type=authorization_code&client_id=******&client_secret=*******&redirect_uri=http%3A%2F%2Fwww.google.fr&code_verifier=Whubzdv9zyTyeqdpEpouWE1QVQ0tGlMpbn3eJpTuHog

Regards,
