Missing variable in `parse_visits` raises error

[nmearl]

When attempting to run the Grizli-Pipeline notebook, an error is raised missing local variables.

Thanks, @nmearl. I think the issue is that a previous pipeline step is not generating FLT files with calwf3 from the RAWs you've downloaded. The auto script is supposed to run my reprocess_wfc3 tools to regenerate the FLTs from the archive RAWs and your run is probably failing that step silently and trying to move on even though no FLTs had been produced.

Can you check that you have all of the dependencies in environment.yml available, including reprocess_wfc3?

A remaining to-do item is to add some checking at the early steps to ensure that the expected products are available and fail gracefully / verbosely if not.
