Redmine › SCM Creator (+Github)

Hello! i’m trying to add my github repo to project.
but get different errors like a “500 internal error”? but no error messages in apache log
I’ve also tried start rails directly via
rails s -e production
and get the next error

NoMethodError (undefined method `[]' for nil:NilClass):
app/controllers/repositories_controller.rb:55:in `create’

could you please help me?
