The Delta Import on an IDB 5.1 MA is failing and returning the following stack trace:

The extensible extension returned an unsupported error.

The stack trace is:

Previously this issue was under control by occasionally doing full imports but the delta imports are no longer functioning at all and failing on each run.

When the delta imports were running each run would have a number of staging errors from trying to recreate connectors that've already been created and we can see on other IDB MA's in the environment that each delta import is computing the same items each run.

Thanks,
Tom
