value: "some initital value"

```
'Deployment.apps "<deployment name>" is invalid: spec.template.spec.containers[0].env[31].valueFrom:
Invalid value: "": may not be specified when `value` is not empty'
```

- You must install the correct init container for your application’s container platform. For example, _lightruncom/k8s-operator-init-java-agent-`linux`:1.7.0-init.0_.
