Description David Nind 2022-11-10 01:44:10 UTC
When clicking on the 'Show MARC' action from the list of records to be modified using Cataloguing > Batch record modification, it shows as 'Loading' and does not complete the display of the modified MARC record.

In the web developer tools an error is displayed:

14:24:26.131 XHR GET http://127.0.0.1:8081/cgi-bin/koha/svc/records/preview?record_type=biblio&record_id=262&mmtid=3&overlay_context=batchmod
[HTTP/1.1 500 Internal Server Error 87ms]

To replicate using koha-testing-docker (KTD):
1. Add a MARC modification template (Cataloguing > MARC modification templates > New template > give it a name and click submit > add a 'New action" (for example: Add new 500$a with value 'OK')).
2. Modify a batch of records (Cataloguing > Batch record modification):
   - For 'Enter a list of record numbers' enter 17 and 262 (sample data for KTD)
   - Choose the template you created in step 1
   - Press Continue
3. Enable the web developer tools console.
3. From the results list, click on 'Show MARC'.
4. On the modal window, note that the spinner says 'Loading', and doesn't complete the display of the MARC.
5. Note that in the web developer tools console there is an error:
   14:24:26.131 XHR GET http://127.0.0.1:8081/cgi-bin/koha/svc/records/preview?record_type=biblio&record_id=262&mmtid=3&overlay_context=batchmod
[HTTP/1.1 500 Internal Server Error 87ms]

It looks to me like the problem might be that we are trying to use the templates on the record we view there (preview of changes) and that this failes.

My action was a simple "delete field xxx"

Can't call method "field" on an undefined value at /kohadevbox/koha/Koha/SimpleMARC.pm line 534
