No access to OAuth2 protected API Rules
If you upgraded to Kyma 2.0 and use the evaluation profile, you could lose access to your OAuth2 protected APIRules. You may get
401 Unauthorized with the
client_id unknown error when fetching a token for your OAuth2 Client resources.
Kyma 2.0 comes with a bumped Ory Hydra version. The update enforced a restart of Ory Hydra and Ory Hydra Maester Pods. As Ory Hydra in the evaluation profile uses an in-memory database (IMBD), the previously created OAuth2 client resources might be no longer available in the Hydra database.
Restart the Ory Hydra Maester Pods to trigger Ory to recreate the OAuth2 client resources. Use the following command:
kubectl rollout restart deployment ory-hydra-maester -n kyma-system
