Better Errors Gem not working in local browser, no errors visible

Question

I added the Better Errors gem to my gemfile like as seen in my gemfile below, and ran bundle and saw Using better_errors 1.1.0 and restarted my server several t

Answer 1

I am running vagrant, rails 5 and ruby 2.3 and I added the below to my config/environments/development.rb and got it working.

  # Allow usage of better_errors on Vagrant
  BetterErrors::Middleware.allow_ip! "10.0.2.2"

  # Show full error reports and disable caching.
  config.consider_all_requests_local = true

Same answers as above but just wanted to confirm it for anyone running the rails 5 beta.

Answer 2

in addition for all better you need to add this to your config/environments/development.rb:

BetterErrors::Middleware.allow_ip! "TRUSTED_IP" where "trusted_ip" is "REMOTE_ADDR" in default error page for me it's 10.0.2.2

Answer 3

In the file app/config/environments/development.rb do you have this line present in the code ?

# Show full error reports and disable caching.
config.consider_all_requests_local = true

Answer 4

Valerie -- are you on a virtual machine? Better errors can sometimes not work well with VMs.

The solution I've found is this:

First, in your app's config/environments/development.rb (anywhere inside the configure do), add:

BetterErrors::Middleware.allow_ip! ENV['TRUSTED_IP'] if ENV['TRUSTED_IP']

Then you need to define that environment variable. Find your remote IP by firing up a browser, hitting the old error page (just throw a raise in a controller or something), and finding the "REMOTE_ADDR" in the error page's "Show env dump" section. Then copy that IP and set it as an ENV variable (in your .env or application.yml file, or wherever you keep those).

Note -- DO NOT add that to production. It's unnecessary at best (Better Errors should only be run/included in development -- as you've ensured above).

Then restart your server. Any chance that fixes it?

Answer 5

With Vagrant, add this to your app's config/environments/development.rb (anywhere inside the configure block):

BetterErrors::Middleware.allow_ip! "0.0.0.0/0"

Then restart your server.

(This is just a slight variation on Sasha's solution.)

DO NOT add this to your production environment!
