After upgrading the kong to 2.6.0 and kong ingress controller to 2.0.5 and 2.0.6, the ingress controller is giving the following error:

time="2021-12-07T09:28:24Z" level=error msg="failed to fetch KongPlugin: no KongPlugin or KongClusterPlugin was found" kongplugin_name=oidc kongplugin_namespace=default subsystem=proxy-cache-resolver time="2021-12-07T09:28:27Z" level=error msg="failed to fetch KongPlugin: no KongPlugin or KongClusterPlugin was found" kongplugin_name=oidc kongplugin_namespace=apps subsystem=proxy-cache-resolver time="2021-12-07T09:28:27Z" level=error msg="failed to fetch KongPlugin: no KongPlugin or KongClusterPlugin was found" kongplugin_name=oidc kongplugin_namespace=default subsystem=proxy-cache-resolver
The configuration for the OIDC plugin is:
apiVersion: configuration.konghq.com/v1 config: client_id: test client_secret: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx discovery: https://keycloak.abc.com/auth/realms/xxxx/.well-known/openid-configuration introspection_endpoint: https://keycloak.abc.com/auth/realms/xxxx/protocol/openid-connect/token/introspect realm: test scope: openid kind: KongClusterPlugin metadata: name: oidc plugin: oidc

The env variable set in of kong:
KONG_PLUGINS: bundled,oidc

Please suggest whats wrong here

@cristichiru Can you please suggest the solution for above issue?

[cristichiru]

I do not have such problems. Perhaps your KongPlugin is in the wrong namespace (not in default)?

kubectl get KongPlugin -A?

Thanks @cristichiru for reverting. I fixed the issue by adding the annotations to the kong cluster plugin as follows:

kubernetes.io/ingress.class: kong
