I'm trying to test it but getting the following error on launch. Has anybody experienced this?

Yes, this issue is the reason why we temporarily disabled the discovery and ecommerce plugins on the quince demo server.

@regisb I have a pending PR for discovery for Django 4.2 upgrade. What do you think about merging it now?

I can't verify the build before the merge but I feel like it's a bad idea to merge w/o at least local test.
