Invalid CSRF Token error in Better Errors console #476
Description
I'm running Rails 6.0.3.3. I'm using TurboLinks 5.2.0, StimulusJS 1.1.1, and rails-ujs 6.0.3 via Webpacker 5.2.1, and not directly using Sprockets (except for ActiveAdmin). Browser is Safari 13.1.2 on macOS 10.15.6.
My layout includes output of csrf_meta_tags in the <head> section, and my form includes the authenticity_token hidden field.
When I attempt to trigger BetterErrors in a controller action (update), it comes up enough that I see a stack frame, but I don't see the source view / REPL / request info / locals / instance vars on the right. I only see an error about "Invalid CSRF Token". The /__better_errors endpoint is available and it works fine, however.
The problem does not occur with BetterErrors 2.7.1.
I'm not sure If I've got something subtly wrong, or if there's a bug (possibly related to TurboLinks, or the use of Webpacker).
What information can I provide to help diagnose this issue?
