Status Code 400 when try to login by Twitch OIDC

muravyov.alexey

On free FA version in docker I have setup OIDC connection for twitch

When I press "Login with OpenID Connect" I get error "A request to the OpenID Connect Token API has failed. Unable to complete this login request."
above the login form

In System > Event log I see this

OpenID Connect IdP Response Debug Log for [OIDC Twitch] [27860663-db55-4319-9da4-9b32df06cb8d]
Call the configured Token endpoint [https://id.twitch.tv/oauth2/token]
GMT Endpoint returned status code [400]
The response was not successful, see the error event log.

and this

Request to the [https://id.twitch.tv/oauth2/token] endpoint failed. Status code [400].
Error response is 
{
  "status" : 400,
  "message" : "missing client secret"
}

this is OIDC settings
!

Why I get this error if I have filled client secret?

Thanks for advice,
Alexey

The reason was 'Client authentication' option. It should be Post method.
But error message mesleads

Glad you figured this out. This might be in the domain of Twitch as they are the ones returning that error code to FusionAuth.

On paid editions, we do have a guide that you can follow for the Twitch provider (sounds as though you may be aware)

Thanks,
