Description

We are seeing several errors come thru empty

"Operation": "TryWriteMultiPackIndex",
"packDir": "XXXX",
"Errors": "",
"Output": "",
"ErrorMessage": ""

The code was changed in this commit here

We should investigate why these errors are empty and perhaps add the returnCode.

Example MountIds:
