Has anyone else encountered this "None of the columns used for mapping matches with columns in uploaded file" error when using the DMF REST API? Any suggestions why it happens please?
We're seeing this on 20-40% of executions when running in reasonably quick succession (6-10 executions per minute) in a Tier 4 environment, with no clear pattern of the first or the last executions in a given period being the ones to fail (i.e. failures are mixed in with successes), and if we import the failing packages through the UI, the error doesn't occur, so I'm pretty confident there's nothing directly wrong with the input data files or the metadata XML files that accompany them in the zip. With little expectation, we added a brief delay between the blob upload API call and the import from package API call in case the upload was somehow incomplete, but that didn't seem to help (and hasn't been necessary before in my experience of using the REST API). Any thoughts welcome
