Use of an exclusion under an arrow that has multiple resources may resolve to NO_PERMISSION
when permission is expected.
For example, given this schema:
definition user {}
definition folder {
relation member: user
relation banned: user
permission view = member - banned
}
definition resource {
relation folder: folder
permission view = folder->view
}
If the resource exists under multiple folders and the user has access to view more than a single folder, SpiceDB may report the user does not have access due to a failure in the exclusion dispatcher to request that all the folders in which the user is a member be returned
Permission is returned as NO_PERMISSION
when PERMISSION
is expected on the CheckPermission
API.
