[Koha] Item Inventory Number Error 500

[Tadas G]

Hello,

I don't remember exactly but I'm upgrading from Koha 20.11
<https://koha-community.org/koha-20-11-15-released/> to Koha 21.05
<https://koha-community.org/koha-21-05-11-released/>.
Install English langauge and I did not change anything.
I think the problem is due to my use of UNIMARC
But my country use UNIMARC


Maybe I would help to run misc/batchRebuildBiblioTables.pl or other and
repair mappings?

Or how else should I mapping biblionumber?

Thanks for the help
