it would be nice to have more informations exposed than just a stack trace that is not helping at all while debugging

[eric-carlsson]

Encountered the same issue after updating the provider to v1.0.0. This seems to be caused by a breaking change to controller-runtime, see kubernetes-sigs/controller-runtime#2622. To fix this it seems we should pass a no-op logger explicitly.

---

@oliver-hofmann-cistec-com by updating the DeploymentRuntimeConfig to pass the --debug flag I can get relevant log output (such as error messages returned by the Vault API) .

apiVersion: pkg.crossplane.io/v1beta1
kind: DeploymentRuntimeConfig
metadata:
  name: vault
spec:
  deploymentTemplate:
    spec:
      selector: {}
      template:
        ...
        spec:
          containers:
            - args: ["--debug"]

However, as mentioned by the code comment this produces extremely verbose output by controller-runtime. It would be nice to have an in-between option where we get errors messages returned by terraform without the rest of the debug information.
