Rails 5.2 exceptions not showing

Question

I upgraded from 5.1 to 5.2 and now my exceptions are not showing, and I'm seeing the 500 error page, as if I had config.consider_all_requests_local set to false... it's set to true in my development.rb however.

Also, as a sidenote, when the exception happens theres literally 10 seconds of log output in the terminal before rails responds. It's so much log output that I can't even scroll to see if the error is being triggered by something else.

without a stack trace I'm not sure how to help? – Cowry

When I scroll to the top of the 10 seconds of output, it's the normal exception of whatever I break to test it (for instance, forcing an image filename to be wrong). The problem isnt the exception itself, its that there is no exception showing... I see the rails 500 error page that normally shows in production (public/500.html) – Lucrative

dit you check for application.rb for exception config? – Lager

I manually copied and replaced every file from a fresh rails 5.2 app, so nothing is different from the default from what i can see – Lucrative

I submitted an issue for this in rails repo github.com/rails/rails/issues/32578 – Stefanistefania

Answer 1

To all the people that find this... here is the problem. I had to remove the web-console gem from the gemfile (leftover from previous Rails versions), and it works now.

gem 'web-console', '>= 3.3.0'

Answer 2

Edit your Gemfile with gem 'web-console' and remove version. Run `bundle install'

Answer 3

For me this was an issue with the remotipart and web-console gems. I was able to downgrade remotipart and all is well.

gem 'remotipart', '1.3.0'
