Ruby on Rails application could not be started

Question

Hi dear stackers,

I'm trying to deploy some changes, and I just cannot see them as the URL I got sends me on a Phusion error page "Ruby on Rails application could not be started".

When I check the logs, I get something like this:

Exception ArgumentError in PhusionPassenger::Railz::ApplicationSpawner (syntax error on line 36, col 1: ` sdc_id: dcsvdln1l00000kv1qsmc4oob_1p3v')

I have absolutely no idea about what's going on, any help would be greatly appreciated.

Thanks in advance,

Rolf

P.S.: the whole trace

Without more info it looks like you have an error in a yaml file somewhere. Perhaps there was a conflict that didn't get resolved? Do a grep on sdc_id and see what you see.
