We have an integration using the HubSpot connector, pushing data from a CSV file on an SFTP server into HubSpot. We're using a file mask to identify the daily file to import. However, we're routinely getting an error saying "Integration failed: There was a problem with the request."

If I manually re-run the sync as soon as I get the error notification, it runs just fine. Is there anything I can do to avoid the error in the first place?
