Bug reports:

When using Apartment (multi-tenancy gem), any model that is shared among all tenants (i.e. in the 'public' schema) return an error 500 (PG::SyntaxError) when trying to query the API. This issue only happens with shared models, and not with tenant-specific models. The issue lies in the way jsonapi-resources writes its queries, e.g:

Internal Server Error: PG::SyntaxError: ERROR:  syntax error at or near "."
LINE 1: SELECT public.accounts.id AS public.accounts_id FROM "public...

The whole query is:

SELECT public.accounts.id AS public.accounts_id FROM "public"."accounts" WHERE "public"."accounts" = $1

SELECT public.accounts.id AS public.accounts_id FROM "public"."accounts" WHERE "public"."accounts" = $1

The bold part is the issue. There should be no dot in the AS statement. public.accounts_id should be public_accounts_id or just accounts_id.

This should be a trivial fix, but I just don't know where in the gem code queries are generated.

No source file or test is named. Start by reproducing the Apartment shared-model query with the listed Ruby, Rails, and jsonapi-resources versions, then trace the query generation that produces the shown SELECT. Done means the generated alias no longer contains a dot and the shared model API query succeeds.
