Request History does not work with Channels

Hello,

I remember in the past at one point I got the request history panel working, but now if I need to use it, it won’t work.

On the front end I have enabled: History, Versions, Time, and SQL panels.

Now if I click on the History tab, then there no rows. And if i click on the Refresh button, i get 400 error:

I have no idea what I am doing wrong or how to troubleshoot that problem. Any suggestions, what should I try next?

Dependencies: Django==3.1.3 django_debug_toolbar==3.1.1

Edited:

Environment: Docker python:3.9.0-slim

Configuration:

@KStenK There’s definitely a chance that the toolbar will not work with channels given it runs with multiple processes and the toolbar’s data is stored in memory.

@KStenK You can get the request history panel to work with channels by setting RENDER_PANELS to False. The names of the functions and settings seems to be off here. The problem is that channels is setting request.META["wsgi.multiprocess"] to True. By configuring RENDER_PANELS to False, you’ll bypass that.
