    customDataSecretRef:
      key: customData
      name: greatScript
      namespace: crossplane-system

Steps to Reproduce

1. Deploy the Manifest and make sure a secret called greatScript in namespace: crossplane-system with a key - customData exists.
2. The key should be only encoded once (base64). to verify that, decode it and make sure you got the script in plain text.
3. an error will pop up saying Azure API can only accept bae64 encoded values.
4. Delete the resource, and try again only this time, encode customData script twice with a base64 encoder, now it'll work.

What happened?

Only when the customData is double encoded the resource works.
