Deleting a service key results in unwanted error #4173
Description
What happened
Create a managed service instance, create a service key, then deete the key
- cf create-service example-service example-plan myinstance
- cf create-service-key myinstance mykey
- cf delete-service-key myinstance mykey
The last command above returns a confusing error, but when I list the service keys for "myinstance" the key being deleted is gone
What did I expect ot happen
Deleting the service key should have succeeded
Dev notes
- When deleting the binding our handler does not differentiate between app and key types and always tries to lookup the app. However when the binding type is "key", the app ref is an empty string, so no app can be looked up
