Rails 5.0.0.beta2 API Exits due to undefined method in logger_silence [activesupport]

[OkySabeni]

This is the error that I get:

It's a new app and it just start failing.

Sample App is zipped. I remove the json file because it contains potentially sensitive information

Can you provide a sample application to reproduce this error, or the CLI commands you used to generate the app?

[OkySabeni]

Sure @maclover7 I attached a sample zip and the command I use.

[maclover7]

I am able to reproduce the error you are seeing using the application you provided... Can you provide the commands you used to generate the application? The line which is causing your error (lib/active_support/logger_silence.rb:23) hasn't been edited for months, so I think that the error may be laying hidden somewhere else...

[OkySabeni]

I'll have to go from my memory.

rails new DevServer --api

That's pretty much it. I did switch over to using postgres. I also set ruby 2.3.0 and rails_12 factor gem in Gemfile. Someone in SO also have this issue so it's not unique to me.

http://stackoverflow.com/questions/35280048/first-time-using-rails-5-trouble-with-tsort-each

Let me know if you need more info.

[maclover7]

Generated a new app locally, and coming up with rails_12factor as the causer of your error. Closing this as a third party issue.

I don't think this is a bug from rails_12factor. I have the gem installed and I can run Rails 5 just fine.
