Hello Jacobs.smith,

Not sure about your complete code/requirement(as you haven't shown us) but seems like it may be code is executing a process into a sub-shell then there it is expecting a variable to be passed rather than it gets passed while running the script.

Thanks,

NAME
lp-shell - Open an interactive launchpadlib shell. SYNOPSIS
lp-shell [-a] [-cPROGRAM] [--python] [--ipython] [service] [LP API version] DESCRIPTION
lp-shell opens an interactive Python shell with a launchpadlib.Launchpad object "lp" which is ready for use. It authenticates against Launchpad with the consumer name "udt-lp-shell". When using lp-shell with the -a option it will use the anonymous login from launchpadlib.Launchpad. By default lp-shell connects to the "production" Launchpad service using the "1.0" LP API version. If you want to connect to another Launchpad service, call lp-shell with the service name as the second argument. lp-shell supports all ser- vices known by launchpadlib Python module. Currently known are (list can be incomplete or outdated): "production", "staging", "dogfood". A different LP API version can be selected by passing the API version to use as the third argument. Current supported are: "beta", "1.0" and "devel". OPTIONS
-a Login anonymously into Launchpad. -c PROGRAM Don't enter a shell but only run the specified Python program and exit. --ipython Use an ipython shell if available (default). --python Use a regular python shell. AUTHORS
