https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=31535 --- Comment #7 from Joonas Kylmälä <joonas.kylmala@iki.fi> --- Created attachment 140464 --> https://bugs.koha-community.org/bugzilla3/attachment.cgi?id=140464&action=edit Bug 31535: Fix warning - uninitialized value in string ne (MARCdetail.pl) Spotted at line 183 (older Koha version). Test plan: You need a NULL in the tab column of marc_subfield_structure. Hit this page and check the logs. This might convince you easier: my $tabloop=0; my $x; print "Empty string - True\n" if ( $x // q{} ) ne $tabloop; print "Zero - True\n" if ( $x // '0' ) ne $tabloop; You should only see: Empty string - True proving that defaulting to '0' would be a game changer.
