Do you have a full stack trace maybe? Without it or the test data it'll be hard to pinpoint the exact issue.

Hi, the issue arose when trying to export DMs when you had a conversation with yourself in your list of conversations. Those had a list of usernames containing only your username that got filtered out which led to this exception. I pushed a fix for it in #4.
