Is it expected that if an empty string is provided for a

optional_relation.relation

in a resource filter that it filters out all relations? e.g. using postman with

ReadRelationships

{
  "relationship_filter": {
    "resource_type": "auth/organisation",
    "optional_resource_id": "57073d44-8a5a-4294-9a29-54dde8721fe6",
    "optional_subject_filter": {
      "subject_type": "auth/staff",
      "optional_subject_id": "",
      "optional_relation": {
        "relation": ""
      }
    }
  }
}

Returns no relations, but if I remove

optional_relation

completely they are returned It's not super intuitive because providing an empty string for

optional_subject_id

does not behave the same, instead it is ignored Just trying to figure out if this is a SpiceDB bug or the .NET client needs a fix to not set

optional_relation

when it's given an empty string edit: relevant info, the relation is on

staff#user

, presumably it will return only direct relations with the empty filter? Which may explain this behaviour.
