Sidekiq: /sidekiq Redirects to RoutingError

[natew]

In my routes.rb:

require 'sidekiq/web'
  mount Sidekiq::Web => '/sidekiq'

When attempting to reach /sidekiq I get a no route found error. Using thin+rails3.2+ruby1.9.3. I can see it actually is running the redirect, but then for some reason just not reaching the controller from there.

Started GET "/sidekiq" for 127.0.0.1 at 2012-04-29 01:52:03 -0700

That's pretty weird that it would resolve /sidekiq and then immediately not resolve /sidekiq. I'm stumped.

[natew]

My rake:routes looks fine....

sidekiq_web        /sidekiq                          Sidekiq::Web

I tried removing my other routes, no luck, going to try removing other gems...

Edit: no luck removing gems.

[mperham]

I know this sounds crazy but does it work if you just directly request "/sidekiq/"?

[natew]

Ah ok, so tried it on a fresh rails app and it works...

[natew]

Haha no it does not, same error as above but without the redirect.

Edit: Not really sure... tried removing all libraries, routes, gems, config files, and booting from webbrick and still getting it.

[mperham]

Did you add the slim and sass gems as the Monitoring page notes?

[natew]

Yes, have them both. Still poking around, emptying application controller was no help.

Tried removing this from web.rb:

return [301, { 'Location' => "#{env['SCRIPT_NAME']}/" }, ['redirecting']] if env['SCRIPT_NAME'] == env['REQUEST_PATH']

Now it doesn't redirect, but still return the error from either url.

[natew]

Really unsure here as to whats happening.. something with Sinatra is my best guess. Anything I could try out in the console to help figure it out?

[mperham]

Not sure what else to say here. Plenty of people are using the web UI successfully so it must be something in your environment but I'm out for ideas to debug. I even tried using thin locally to see if that was a problem:

=> Booting Thin
=> Rails 3.2.2 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
>> Thin web server (v1.3.1 codename Triple Espresso)
>> Maximum connections set to 1024
>> Listening on 0.0.0.0:3000, CTRL+C to stop


Started GET "/sidekiq/" for 127.0.0.1 at 2012-05-02 20:27:44 -0700


Started GET "/sidekiq/assets/application.css" for 127.0.0.1 at 2012-05-02 20:27:44 -0700


Started GET "/sidekiq/assets/application.js" for 127.0.0.1 at 2012-05-02 20:27:44 -0700

Works fine.

[smostovoy]

this can be if you added constraints and don't pass them

[clarif]

A clue... I had a similar issue and was facing at the same time erractic issues with the Redis connection: in some cases, Redis was not responding (connection timeout). In that situation (e.g. sidekiq web well configured and Redis not reachable), the sidekiq monitoring interface was not available and logs were showing 'No route matches [GET] "/sidekiq"'.

If it can help...

[danigb]

I have the same issue and was related with the gem 'rails-translate-routes'. When I removed it from the router, it all worked again. I'll try to find a solution.

[josal]

Same problem here, this time related with the gem 'route_translator', similar to yours @danigb. I'll try to find a solution as well.

[snoblenet]

Any progress on this issue?

I'm getting:

17:33:48 web.1    | I, [2014-01-21T17:33:48.140001 #1241]  INFO -- : Started GET "/sidekiq" for 127.0.0.1 at 2014-01-21 17:33:48 +1100

I'm switched to mini_magick and PG::Connection.isthreadsafe returns true. I'm not using any of the gems mentioned above. There is no mention of trouble connecting to Redis in my logs. I've not added any constraints to the route.

I've tried disabling various gems as well as removing the Profile and unicorn refs.

For what it's worth...
I had in my gem file:

group :production do
  gem 'dalli'                   # memcached
  gem 'memcachier'              # heroku add-on for auto config of dalli
  gem 'unicorn'
  gem 'rails_12factor'          # https://devcenter.heroku.com/articles/rails4
end

I commented out gem 'unicorn' and it started working... but obviously not necessarily a "fix" per say but wanted to share this finding for now.

[kristenhazard]

  require 'sidekiq/web'
  authenticate :user, lambda { |u| u.superuser? } do
    mount Sidekiq::Web, at: '/sidekiq'
  end

This happened to me when my user didn't pass the authenticate code above: u.superuser?. This might help people understand what's happening for them even though I don't think it's the same issue.
