[Koha] search_for_data_inconsistencies.pl: Can't call method "get_column"

[Michael Kuhn]

Hi

We are using Koha 20.11.02 with MariaDB 10.3.39, running on Debian 
GNU/Linux 10.

When calling the script "search_for_data_inconsistencies.pl" the only 
output is the following:

$ sudo koha-shell -c "perl 
/usr/share/koha/bin/maintenance/search_for_data_inconsistencies.pl" 
instancename
Can't call method "get_column" on an undefined value at 
/usr/share/koha/bin/maintenance/search_for_data_inconsistencies.pl line 157.

Does anyone know how to solve this problem?

Best wishes: Michael
