Plugins » Foreman Remote Execution

When the loglevel in /etc/foreman-proxy/settings.yml is set to WARN (and probably also with UNKNOWN), the smart-proxy script feature fails to load.

The relevant error in the log is:

2024-07-30T08:41:23 [E] Couldn't enable 'script'
2024-07-30T08:41:23 [W] Error details for Couldn't enable 'script': <NoMethodError>: undefined method `last' for nil:NilClass

• Install a smart-proxy with the remote-execution-script feature
• set log level to "WARN" in /etc/foreman-proxy/settings.yml
• Restart the smart-proxy service

• Either this should be caught via https://github.com/theforeman/smart_proxy_remote_execution_ssh/blob/master/lib/smart_proxy_remote_execution_ssh.rb#L81 and reported via a proper error message or
• Loglevel should be dropped to the next less-verbose level silently without a failure to load the entire module

This was found with Remote Execution 12.0.5 and remote_execution_ssh 0.10.4, but looking at the code the relevant parts were not changed since then.
