I use the following query:

query {next_items_page (cursor: “cursor_string”, limit: 50) {cursor items {id name column_values {id value …on MirrorValue {display_value} }}}}

the query works as expected if we neglect the term “…on MirrorValue {display_value}”, but returns an internal server error 500 when included.

Is there a way that I can make this work?
