Multiple casbin policy definitions in model fail when evaluated

Question

I'm testing out a very simple permissions model, but seems like two policy_definition values in a model can not be handled in NodeJS? Is there another approach to the described model ?

Model description: users belong to an organization, organizations have subscription plans and plans have a list of features that users should be able to access.

The questions I would be asking are:

1. Can user:1 access feature:A --> true
2. Can user:1 acess feature:C --> false
3. Can user:2 access feature:A --> false

I have the following definitions and data

model.conf

[request_definition]
r = sub, obj, act

[policy_definition]
p = sub, obj, act
p2 = p2_sub, p2_obj, p2_act  # prefixed with `p2` for debuggability 

[role_definition]
g = _, _

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

[matchers]
m = g(r.sub, p2.p2_sub) && r.sub == p.obj && r.act == p.act && r.obj == p2.p2_obj

policy.csv

p, user:1, organization:1, view
p2, plan:1, feature:A, view
g, organization:1, plan:1

app.js

...
const e = await newEnforcer('model.conf', 'policy.csv');
const result = await e.enforce(sub, obj, act);
console.log(result);
....

When running the above code, it's failing with this message:

TypeError: Cannot read properties of undefined (reading 'p2_sub')

If I remove p2 policy from model.conf and policy.csv all works OK (but of course doesn't produce correct result)
