Something's going wrong at Line 109 in tunnel.bash

Hi,
Thanks for script. Must have taken you ages to write.
I've got a problem with Line 109 in tunnel.bash
Something's up with creating the command to send to the remote side to check the port.
For me the script is crashing out on the SSH command.
It's 01:00 so I'm going to give up for the moment...

This works (where I've substituted ls -al ) !!
isProcessRunning="$(ssh ${identityOption} -n "${remoteUser}@${remoteHost}" "ls -al")"

Command Line is:
./tunnel.bash --local-port 22 --remote-port 2223 --remote-to-local --remote-user XXX --remote-host 99.99.99.99 --identity-file "/home/XXX/.ssh/id_rsa"

OK, found it... On my Ubuntu 18.04 with Bash 4, using "set -e" causes script to end if script uses a non-zero Return, which you do in the Utils library.
I didn't realise that !!
