Exception/505 when visiting conversations tab

[SomeMashedPotatoes]

First off, great work on this project, it was working perfectly up until I went to the conversations tab to try and view my conversations. I know that I have one conversation but I could not even view the page and I instead get a 500 page. Here is the output, looking at the logs it seems like it has to do with the jinja formatting.

It seems that it is possible that a conversation might not contain a user message object. I'll have to now check for that before rendering the template to avoid exceptions like this.

Hmm I tried running it again with the new changes and I am getting the same error. My account does have 1 conversation with just 1 message sent on my end.

I understand what's happening now. It's because you have just a single conversation with your account. I never encounted this before because I've always had more than one conversation to display.

Try using commit fc66af2 and see if that fixes the bug.
