getting certificate for webhook: failure while waiting for approval: timed out waiting for the condition

[ghost]

Hi,
When trying to install greenplum operator(minimal) getting the following error:
{"level":"ERROR","ts":"2022-05-23T12:08:00.815Z","logger":"setup","msg":"error","error":"getting certificate for webhook: failure while waiting for approval: timed out waiting for the condition","errorCauses":[{"error":"getting certificate for webhook: failure while waiting for approval: timed out waiting for the condition"}],"stacktrace":"github.com/go-logr/zapr.(*zapLogger).Error\n\t/go/pkg/mod/github.com/go-logr/[email protected]/zapr.go:128\nmain.main\n\t/greenplum-for-kubernetes/greenplum-operator/cmd/greenplumOperator/main.go:35\nruntime.main\n\t/usr/local/go/src/runtime/proc.go:203"}

Does anyone know what could be the problem?

Best,
Oktay
