Thanks for the help salva! As far as debugging the script (when it hangs) is concerned, I’ll use strace.

For the issue where bash was printing error message but my perl script wasn’t, I figured out the mistake I was committing. Instead of

my ($stdout) = $ssh->capture2("~/release/$wrapper");

I should have used

my ($stdout, $errput) = $ssh->capture2("~/release/$wrapper");

I was only checking stdout earlier :)
