Better error page not showing up in dev environment

Short and simple question. When I get an exception while developing my Phoenix based web app I get the 500.html rendered. But I would really love to see the beautiful error page (instead of having to find the information in console).

What could be causing this? At some point a long time ago I think it was working :slight_smile: The debug_errors is set to true in dev.exs and I’ve tried cleaning the project and rebuilding.

As long as debug_errors: true, is set on the endpoint then it should be, I’ve never seen it otherwise as of yet. Do you have a minimal reproducible example that you can put on github for us to test?
