Another question - is it possible to specify additional extensions in the response? We are thinking about exposing some additional metadata with the response and the extensions field seems to be the right fit for this. Is there a way to send the extensions with the responses coming from the server?

Extensions can be specified with the same approach as above by returning a `DataFetcherResult<*>`https://expediagroup.github.io/graphql-kotlin/docs/schema-generator/execution/exceptions#returning-data-and-errors


But the probably more common way is to graphql-java instrumentations:

Thanks, will follow-up on the thread above

initially found the graphql-java ExecutionResult api for this not quite straightforward, so if an instrumentation example is helpful, here's one: https://github.com/trib3/leakycauldron/blob/main/graphql/src/main/kotlin/com/trib3/graphql/execution/RequestIdInstrumentation.kt

Great, thanks for sharing this.
