InternalServerFailureException error message caught in SDK Query Response

I expect the couchbase query error msg to be accessible from the sdk exception.
 
Looks like 5000-5999 series error code exceptions send a generic `InternalServerFailureException`. However, a message does in fact exist describing the error from couchbase. This does not appear to be available through sdk exception on error.
 
Example: a query with missing parameter will send code 5010 and a msg of "Error evaluating filter. - cause: No value for named parameter $test."
 
I would have thought that message would be able to be found from the caught exception.
