I have solved this problem. The problem was in order of request.

When you calling method can of authorizer class, it alwas enforces your request in own order:

enforcer.enforce(this.user, domain, object, action)

And if you have own request order, authorizer.can will throws error.

So I created own library that solves this problem, you can write your request in order which you want. https://github.com/Dias1c/casbin-js/tree/main
