[Koha] Software error: Can't call method "branchname" on an undefined value at /usr/share/koha/lib/C4/Biblio.pm line 1627.

[Jonathan Druart]

Bruck,

My understanding of the error is that you have a field that is mapped
with the "authorised value" branches (that's not a real authorised
value). But at least one of those field has a value that is not a
branchcode defined in your system.

The weird thing is that, by default, only item's fields are mapped
with "branches", 952$a and 952$b
Can you try this SQL query: select tagfield, tagsubfield from
marc_subfield_structure where authorised_value="branches" and tagfield
!= 952;
Does it return something?

To know which value we are searching search, you could also add a
debug statement
    warn $value;
 before
1627             return Koha::Libraries->find($value)->branchname;

Regards,
Jonathan

I search the archive online saw the advice to update the two fields<https://lists.katipo.co.nz/public/koha/2017-September/048966.html> (UPDATE items SET homebranch='LIB', holdingbranch='LIB'). I have done that and did the full reindex. But, that does not seem to have helped. Please advise.
