sidecar injected though no configmap created, therefore init does not come up

[peppe77]

K8S: 1.18
sidecar: 0.1.7

the side-car gets injected though the required configmap is not created, therefore the init does not come up. this only happens in one namespace. similar setup works in 2 other namespaces. some suggestions on which additional logs to enable and check? problem is still happening, so should be fairly easy to get more logs. thanks
