Delete operations are failing with RestApiHandler and NextRequestHandler

[hasan-aa]

Description and expected behavior
When using RestApiHandler with NextRequestHandler delete operations are failing.
RestApiHandler is returning undefined on the body after successful delete.
Then NextRequestHandler is trying to serialize it as JSON and failing.
"message": "An unhandled error occurred: TypeError: Value is not JSON serializable"
