Ruby 3.0 breaks web-console

[perryventas]

Using the activerecord-session_store gem on a Rails 6.1 application with latest Ruby 3.0 seems to break the web-console on development environment and instead renders the public/500.html error page.

How to reproduce:

1. Create a fresh Rails 6.1 application with Ruby 3.0, start webserver and make sure web-console works (e.g. triggering a 404 by entering an unknown URL)

2. Add the `activerecord-session_store` to your Gemfile, run bundle install, restart the rails server and try again to trigger a 404, which will result in displaying the default public/500.html error page:

The console does not show anything suspicious:

Started GET "/asdf" for 127.0.0.1 at 2021-03-07 16:38:37 +0100
   (3.4ms)  SELECT sqlite_version(*)

ActionController::RoutingError (No route matches [GET] "/asdf"):

Downgrading the Ruby version to 2.7.2 fixes the issue.

Thanks in advance

Last time I tried the last release of this gem didn't work with Ruby 3.0 at all, so you got further than I did :)

There's something in master but not released for the issue I was having; see #159 and #171

There seem to be some recent issues in this repo relating to 6.1 as well.

Fwiw I'm using this gem in a Ruby 3.0, Rails 6.1 app myself (ShinyCMS) and it seems fine, but it's not in production use.

2.0.0 was released and contains the Ruby 3.0 compatibility fix.
