Errors are not shown in the browser in Rails 5, no info about the filename and lineno in logs

[januszm]

Rails 5.0.0.rc1

On error I see the standard 'production-like' page:

We're sorry, but something went wrong.

Also, that's all I get in logs:

ActionView::Template::Error (Multiple , attributes specified):

Possibly related to: #472 ?

I've just encountered this. I'm sure it's probably my mistake, but a bit of info about where I went wrong would be helpful!

I'm also seeing this in Rails 5.1.1. Like @januszm, I get an ActionView::Template::Error with no reference to the slim filename or line number anywhere in the stack trace.

Same issue in 5.2.3.

[INFO ] Completed 500 Internal Server Error in 805ms (ActiveRecord: 24.9ms)
[FATAL] ActionView::Template::Error (Object must be a Date, DateTime or Time object. 3661 given.):

No stack trace.

I'm on Rails 6.0.0 using slim 4.0.1. ERB errors are rendered in the web-console, some Slim errors are swallowed up. better_errors works as a replacement.

I'm also experiencing this. In some cases there's no report in the log and not in web-console.
However I have a sentry crash backtrace for one such issue.
In my case it was InvalidPluralizationData exception thrown by i18n library. I don't know where in Rails it gets wrapped into ActionView::Template::Error and why it doesn't show in development. Hope that it helps.

I'm starting a new rails project now, I'll fix it if I see it.
