Environment

OS Version: Ubuntu 22.04
Source or binary build? gz-transport3, 184c3dfbecbadc7bb91ff8293e1cc925b4130668

Description

Expected behavior: When the input message provided to gz topic -p is invalid, it should print an error and quit.
Actual behavior: It prints an error and actually publishes an empty message.

Steps to reproduce

In one terminal, run gz topic -e --json-output -t chatter
In another, run gz toic -t chatter -m gz.msgs.Double -p "0.5"

The first terminal should print {} indicating an empty message was received[
