GKE Config Connector StorageBucket resource times out on kubectl apply - kubernetes

Question

I'm trying to apply the following StorageBucket resource from Google's sample manifest:
apiVersion: storage.cnrm.cloud.google.com/v1alpha2
kind: StorageBucket
metadata:
labels:
label-one: "value-one"
name: dmacthedestroyer-hdjkwhekhjewkjeh-storagebucket-sample
spec:
lifecycleRule:
- action:
type: Delete
condition:
age: 7
versioning:
enabled: true
cors:
- origin: ["http://example.appspot.com"]
responseHeader: ["Content-Type"]
method: ["GET", "HEAD", "DELETE"]
maxAgeSeconds: 3600
The response times out with the following errors:
$ kubectl apply -f sample.yaml
Error from server (Timeout): error when creating "sample.yaml": Timeout: request did not complete within requested timeout 30s
UPDATE:
For some unknown reason, the error message has changed to this:
Error from server (InternalError): error when creating "sample.yaml": Internal error occurred: failed calling webhook "cnrm-deny-unknown-fields-webhook.google.com": Post https://cnrm-validating-webhook-service.cnrm-system.svc:443/deny-unknown-fields?timeout=30s: net/http: TLS handshake timeout
I've tested this on two different networks, with the same error result.
I installed the Config Connector components as described in their documentation, using a dedicated service account with the roles/owner permissions, exactly as stated in the above instructions.
I have successfully deployed IAMServiceAccount and IAMServiceAccountKey resources with this setup.
How should I proceed to troubleshoot this?

Answer 1

My issue was due to an incorrect service account configuration.
In particular, I was assigning the owner role to a different project.
After properly configuring my service account, the timeout errors are resolved.
