hamachi (no parameters, for status) exit code is '1' - why

I'm trying to gather status of hamachi in the backend of a nodejs application under linux.

When I call out to hamachi using exec/execSync, it returns the results in stdout but then returns an exit code of '1'.  This means I have to deal with the result as an error instead of a success (exit code 0).

Is there an actual reason for returning '1' when requesting status using just 'hamachi' on the command line?
