Kong Gateway: Receiving error "entity tags missing fields" error="no namespace" name=openid-connect

We’re currently deployed in DB-less on kubernetes. While installing Kong Gateway with Kong Ingress Controller (KIC), we noticed that our ingress-controller is failing to start up properly.

When reviewing the logs, or the Kubernetes events for the affected resource, we can see a schema violation for the openid-connect plugin stating it is an enterprise-only plugin, surfaced through one of two paths:

As an admission-webhook rejection when applying the resource:

Error from server: error when creating "plugin.yaml": admission webhook "validations.kong.konghq.com" denied the request: openid-connect is an enterprise only plugin

Or as a KongConfigurationApplyFailed Warning Event on the resource if the webhook path is bypassed:

Warning  KongConfigurationApplyFailed  ingress-controller  openid-connect is an enterprise only plugin

How can we resolve this?

This occurs because the openid-connect plugin is only available with a valid Kong Gateway Enterprise license, and no license (or no valid license) is currently loaded on the Gateway/data plane. We can verify this by checking the startup logs for the proxy pod for licensing-related messages.

To resolve this, please redeploy the license and verify the steps.
