SDK22: Lambda + KV Range Scan
Description
In the json streaming lexer the on_complete callback is only called at the end of the results array in a response. If the response does not contain a results array the callback is never called. This causes the response data to be empty when decoded which results in a parsing failure being returned.
It has been observed this is the case with analytics create dataverse queries and possibly other management queries.
