Is there an API endpoint for all import errors?
For example, a user can get these types of errors when importing to a model: no items in a list, failed cells, and unmapped line items, etc.
I've automated imports with a custom script. I've now purposefully introduced errors into my imports so they fail and want the specific errors to be returned when they do.
The way to get detailed error information for an import is to retrieve the dump file when produced. https://anaplanbulkapi20.docs.apiary.io/#Check-for-import-failures has more information.
