Any help would be appreciated here. After upgrading our installation to Koha 22.05.00.000, we are now receiving Zebra indexing errors and no records show in Opac searches. Running "koha-rebuild-zebra -f -v library" yields the following: Zebra configuration information ================================ Zebra biblio directory = /var/lib/koha/library/biblios Zebra authorities directory = /var/lib/koha/library/authorities Koha directory = /usr/share/koha/intranet/cgi-bin Lockfile = /var/lock/koha/library/rebuild/rebuild..LCK BIBLIONUMBER in : 999$c BIBLIOITEMNUMBER in : 999$d ================================ Job started: 16:50:26 skipping authorities ==================== exporting biblio 16:50:27 [00:00:01] ==================== 1Can't call method "subfield" on an undefined value at /usr/share/koha/lib/Koha/Filter/MARC/EmbedItemsAvailability.pm line 75.
