New rails 4.2 installation

I'm encountering this same error, Rails 4.2 Ruby 2.2.0. The error is coming from Sinatra.

After further troubleshooting, I'm convinced the problem is it does not support Mongoid, which is what I'm using. @the-tech-net, are you using Mongoid?

Yes this is the problem. But what is the solution?

Steve Schlotter · Answer 4 · Mon Jan 26 2015 22:18:57 GMT+0800 (China Standard Time)

I suppose somebody with the time and talent could add Mongoid support and submit a pull request. Of which I have neither!

I was having the same issue after upgrading to Rails 4.2. I'm not using Mongoid or Mongo. In my case, I was mounting DelayedJobWeb in config.ru, instead of mounting it as a route in config/routes.rb. I had been doing this on an older version of delayed_job_web for a couple of years. When I followed the instructions in the README to mount it in config/routes.rb, I bypassed this error.
