Hi Everyone, I am new to koha and this community , so not sure if i am sending the mail to the right group. So i've been trying to run koha on a container for some time now, and ive managed to configure everything. Now im trying to import some data that i already have into the koha database, but searching in OPAC doesnt return any results even after i load everything into the database . So i figured i might need to run koha-rebuild-zebra command, but im facing an error . This is the output of koha-rebuild-zebra: Zebra configuration information ================================ Zebra biblio directory = /var/lib/koha/${KOHA_INSTANCE}/biblios Zebra authorities directory = /var/lib/koha/${KOHA_INSTANCE}/authorities Koha directory = /usr/share/koha/intranet/cgi-bin Lockfile = /var/lock/zebra_koha_${KOHA_INSTANCE}/rebuild/rebuild..LCK BIBLIONUMBER in : 999$c BIBLIOITEMNUMBER in : 999$d ================================ skipping authorities ==================== exporting biblio ==================== 58801..............................................................................................

I have checked the user permissions for all files in /var/lib/koha/ and /etc/koha/zebradb and made the owner to ${KOHA_INSTANCE}-koha . I cant seem to find the reason behind this error. I have also checked /etc/koha/zebradb/lang_defs/en and i can see the file sort-string-utf.chr My koha version is 20.11 If someone knows the reason for this error, please do help. If you require any more info regarding my installation or configuration I can provide that. Thanks
