Ssh portal returning 0 for failed commands

[bomoko]

When running commands via ssh calls to the ssh-portal, we're experiencing issues with the return code coming back as zero where we would expect non-zero codes.

Calling the ssh portal with a clearly spurious command, like the one that follows, returns 0 via the ssh-portal, while the lagoon-core ssh service returns 127:

ssh -v -p XXXX project-username@ssh.portal.goes.here service=cli 'IDoNotExist'

This is being observed in ssh portal version 0.27.1
