I forgot to mention that is wrapped in:
my $envelope = { # This is the outer envelope object
  waypointQuery => {
    query =>  $query  # The "query" property of inner envelope holds query
  } # End of inner envelope
}; # End of outer envelope

No, that doesn't do anything.  Oh, but changing the "query =>" line to 
    query => [ $query ]
works.  Funny, I thought I'd tried that already.  Thanks for the hint.
