Getting index out of range due to monthkeys.

date = monthkeys[-1]
IndexError: list index out of range

For some reason the outbox.json file from more recent backups has duplicate 'orderedItems' keys, the first of which is empty, for each record. Consequently, an empty dictionary is created and there's nothing to index, hence the error. You won't notice unless you remove the toots.pk file, or have never run mastodon-data-viewer.py on an unzipped backup.

Running an inline sed on the outbox.json file fixes the problem:

$ sed -i 's/\"orderedItems\":\[\],//' outbox.json
