https://github.com/Koha-Community/Koha/blob/24.05.x/misc/maintenance/search_... probably that the biblio in question doesnt have a biblioitem associated. if thats the cause an extra step could be introduced that prevents calling biblio->biblioitem->biblioitemnumber if biblio->biblioitem is not defined.

Hi

We are using Debian GNU/Linux 12 with Koha 24.05.05.

When running script "search_for_data_inconsistencies.pl" it shows only the following message:

Can't call method "biblioitemnumber" on an undefined value at /usr/share/koha/bin/maintenance/search_for_data_inconsistencies.pl line 152.

What does it mean, how can we find out what's the problem here?
