Details

SpiceDB exclusions can result in no permission returned when permission expected ### Background 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: ```zed 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 ### Impact Permission is returned as `NO_PERMISSION` when `PERMISSION` is expected on the `CheckPermission` API. ### Workarounds None
