Closes #127.

This is a reasonable thing to do, but I don't think it fixes the underlying issue. The query should not be empty because there are chimecal files in /mnt/gong/staging. For some reason these files are not being added to the database when the refresh_archive_index method is called.

Thanks for further clarification on why the query is coming back empty! I will take a further look.

For updates in what is happening here, find_jump was looking for the archive_index.db in /mnt/gong/not_archived which has been deprecated. The underlying issue is hopefully being fixed here: https://github.com/chime-experiment/dias/pull/130/files Do we still want error handling/notifications when this issue comes up? Or shall we close?

I understand from the comments here that "the underlying issue" has been fixed elsewhere. But since the SQL query generally can result in Nones, it can't be wrong to check and handle that case.
