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

[Abdulsalam Yousef]

 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.
