AZ201: Unknown type

A relation's subjects, an invariant, a scope and a test name types the policy declares (type team = app.teams). Declare it, or fix the name.

Reported when the policy is compiled: rowfence check, the editor, rowfence dev.

The mistake

app role app_user
type user = app.users
type folder = app.folders
  owner : person = owner_id
  can view = owner

line 4: folder.owner: unknown type 'person' [AZ201]

Fixed

app role app_user
type user = app.users
type folder = app.folders
  owner : user = owner_id
  can view = owner
