Data Import updates SRS Record (but not Inventory record)

Overview: The following issue is observed in an Iris Hotfix-3 environment (Universidad de Concepcion), but it can also be reproduced in folio-snapshot. Import a MARC file, matching on 001, to update the SRS MARC Bib and related instance. The Instance field mapping profile has no edits in it. It's only trying to update the details controlled by the updated MARC record (fixing some diacritics) - no additional mappings. SRS MARC Bib is updated, but the instance is not. Import shows Completed with errors.

Current workaround Use a different action profile (Update MARC Bib) with a field mapping profile of MARC Bib/Update, with no edits. THAT finally worked

Steps to Reproduce:

1. Log into FOLIO-snapshot-load as diku_admin
2. Import the attached MARC file MusicayNeurocienciaBad.mrc to create SRS MARC and Instance, using the Default - Create Instance and SRS MARC Bib job profile
3. Create a job profile with
   • Match profile: MARC 001 to MARC 001
   • Action profile: Update instance
   • Field mapping profile: for Instance, with no edits in it
4. Go to Inventory and find the HRID of the Instance that was just created
5. Edit the attached MusicayNeurocienciaGood.mrc file to have that HRID in the 001 field
6. Then Import the MusicayNeurocienciaGood.mrc file using the profile created in step 3
7. Check the instance and the SRS MARC to see if they both were updated

Expected Results:

• Instance and SRS MARC should both be updated
• If the instance is not updated, the UI log should show "Error" with some sort of error message on the Instance tab

Actual Results:

• The SRS MARC Bib is updated, but not the Instance.
• UI job shows Completed with errors, but no error noted in the log

Notes from A-M

• I also tried using an Instance field mapping profile with an updated instance status (Cataloged), but that completed with errors also
• And I tried a different action profile (Update MARC Bib) with a field mapping profile of MARC Bib/Update, with no edits. THAT finally worked
• See attached video showing it reproducing in folio-snapshot-load

Of note – we observe stack trace in log for mod-inventory
