Error reading response length from authentication socket

[ceeram]

The following code in check-ssh-agent.sh:

# Show loaded keys
echo "SSH Forwarded keys:"
OUTPUT=$(ssh-add -l 2>&1)
EXITCODE=$?
echo "=> $OUTPUT"

includes an unhandled error with message from ssh-add -l command:

SSH Forwarded keys:
=> Error reading response length from authentication socket.

It actually displays the ssh-agent output as-is (and in this case exactly as expected).

I do empathize with the confusion.... this will be clarified.
