[Koha] Can't Define or display libraries in staff client

Hello All, I'm trying to Define new branches from Koha basic parameters in staff client (http://localhost/cgi-bin/koha/admin/branches.pl), but there are no branches displayed, I guess it's fetched through the API, and the http Get request for http://subdomain.com/api/v1/libraries?_page=1&_per_page=20&q=[]&_match= contains&_order_by=+me.name returned 500 Internal server error! All configurations seem to be good. Is it a compatibility issue? My current env vars are: OS: Debian10 Koha version: 21.11.01.000 Perl Version: 5.02800 Mojoliciou: 9.22 Mojolicious::Plugin::OpenAPI: 5.02 JSON::Validator: 5.05 Has anyone faced this problem before? Thanks in advance.
