Are you using the default lauthz-rbac-model.conf configuration file? I tried to reproduce this error, but did not succeed.

[amitgoldy1]

Yes, I am using default model file. Below are the code:

[request_definition]
r = sub, obj, act

[policy_definition]
p = sub, obj, act

[role_definition]
g = _, _

[policy_effect]
e = some(where (p.eft == allow))

[matchers]
m = g(r.sub, p.sub) && keyMatch2(r.obj, p.obj) && regexMatch(r.act, p.act)

I am using this middleware in web.php file.

Route::group(['middleware' => ['http_request']], function () {
Route::resource('photo', 'PhotoController');
});

@basakest @amitgoldy1 There should be a need to convert the AuthIdentifier to a string ：
