The Microsoft Sites Document Library (Sharepoint Online) Data Destination fails either constantly or intermittently with the following error:
ExceptionLogger - Server-side Error: UncategorizedApiException: No error details from Microsoft Live
This can occur when a very long filepath (i.e. folder and or filename) is defined which exceeds the Microsoft server's character limit. (In one of the cases the limit was reached at 115 characters)
Update the Data Record Document Folder Expression in Microsoft Sites Document Library Data Destination to reduce the folder path to remain within the 115 Character limit. If using DREL, then please verify that the final path will not exceed the limit.
