GraphQL filter location by contacts?

[llamafilm]

I'm trying to figure out a GraphQL filter to return a list of locations which have a certain contact assigned. I thought this should work, but it returns an empty list:

{
  location_list(filters: {contacts: {id: "1"}}) {
    name
    devices {
      id
    }
  }
}

This API query works as expected: /api/dcim/locations/?contact=1

This query returns error: "Unsupported lookup 'name__exact' for GenericRel or join on the field not permitted."

{
  location_list(filters: {contacts:{name:{exact: "MSE"}}}) {
    name
    devices {
      id
    }
  }
}
