Hey guys, trying to get Zitadel working with next, but get this error when I try to sign in (after the redirect):

[next-auth][error][OAUTH_CALLBACK_HANDLER_ERROR]
https://next-auth.js.org/errors#oauth_callback_handler_error server_error {
  error: {
    message: 'server_error',
    stack: 'Error: server_error\n' +

    name: 'Error'
  },
  error_description: 'unable to retrieve client by id',
  providerId: 'zitadel',
  message: 'server_error'
}

Any idea what the problem is?
