EDIFACT Inv: Irregular Invoice line data in EDIFACT invoice file causes import to fail

Environment: Juniper with all hotfixes

Overview:
If a Data Import field mapping profile is created with an empty "Description" field, then EDIFACT import fails.

Workaround: Include something in the description field of any EDIFACT field mapping profile

Steps to Reproduce:

• Log into any FOLIO env with Data Import enabled.
• Go to Settings -> Data Import -> Field Mapping Profile -> Create EDIFACT Invoice Field mapping profile with empty Description
• Link that field mapping profile to an action profile to Create Invoice. Do not include a description in the Action profile.
• Link that action profile to a job profile for Creating Invoices from EDIFACT file. Do not include a description in the Job profile.
• Job profile field mapping with an empty description
  
• Import an EDIFACT file using that job profile

Expected Results:
Data Import should not fail because of empty "Description" in field mapping profile

Actual Results:
Data Import fails with Completed with Error. Following error was seen in mod-invoice
