This will certainly work:

   my ($answer, $trace) = try { $call->request(%args) };

What is the scope of the change of __WARN__?
  local $SIG{__WARN__} = sub {...};

Log::Report's try{} will catch WARN and DIE and translate those into
real exceptions.  See Log::Report::Die for the translation.  If you
block the info from flowing to the try{}   (the compiled client has
one inside as well), then not all errors will get to the trace object.
