502 error - chatables

[Moin]

I got a 502 error here on Meta today. Apart from the pop up, I didn’t notice any unexpected behavior. I am not really sure what caused this, and I am not consistently able to reproduce it, but I was able to trigger it a few times.

Here is what I did:

1. I used the + in the sidebar to open the DM chat with someone I talked to before but who is currently not in my sidebar.
2. I used the full-screen chat button.
3. I changed the size of the browser window so it was smaller.
4. I made the browser window full screen again.
5. I switched from full-screen chat back to the small chat window.
6. About 7 seconds later, I saw
   
   

The browser console showed:

That’s all I have. I hope someone can make more of it than I can. If it helps, I have a video showing how I reproduced this.

I used the + in the sidebar to open the DM chat with someone I talked to before but who is currently not in my sidebar.

Maybe it’s caused by this step? Is it possible that it happens when you search for someone in that chat filter?

I think I found the step I need to reproduce: When I type “L” into the chat filter the error appears about 30 seconds later
