Try to print xmlString at this point (or view it in the debugger).
Does it contain the expected XML? If yes, the problem is somewhere
downstream (your code, gRPC, etc). If it is empty, then the issues
is likely with the way you have setup the serialization. Try to
replace it with just the call to the generated serialization function
(without any custom error handlers, etc). If that makes a difference,
then the problem is likely with your serialization code. (Perhaps
there is an error but your error handler ignores it?)
