Instance Method Details

#execute_multiplex(multiplex:) ⇒ Object

All queries pass through a multiplex, even if only one query is executed github.com/rmosolgo/graphql-ruby/blob/43e377b5b743a9102381d6ad3adaaed13ff5b6dd/lib/graphql/schema.rb#L1303

Instrumenting the multiplex ensures that all queries have been fully exectued meaning that query.result is present. We need query.result to know if the query was successful or not in metrics and to include the errors in the logs.
