Need better errors when running something on nothing
When you try to run a manual element with no commands define, it will try to run the strip-commands.
Because the user had no clue that the runtime needed to have a shell and actually, be a runtime; at least an imported one (reasonable for a newcomer), we have a weird error.
Would be better to tell the user that they need a runtime, than to just blindly execute the non-existing shell.
Error example:
