Prometheus Operator release failed

Lately I’ve been getting up-to-speed on Prometheus. That is, the prometheus-operator chart installed via helm:

NAME                            CHART VERSION   APP VERSION
stable/prometheus-operator      6.11.0          0.32.0

I’m seeing an error, though:

Error: release prometheus failed: rpc error: code = Canceled desc = grpc: the client connection is closing

The workaround for this, as Github user cu12 has so kindly pointed out, is to disable admission webhook support (e.g., --set prometheusOperator.admissionWebhooks.enabled=false).
