I really need help debugging an error I’m getting with Passenger on Apache.
I’ve just made a fresh install of Ubuntu 10.4 and have Apache, Ruby and Passenger installed. I’m trying to run a simple rack app but keep getting this error in my Apache
[Tue Sep 28 05:54:41 2010] [error] [client 188.8.131.52] Premature end of script headers:
The error then continues with
The backend application (process 25574) did not send a valid HTTP response; instead, it sent nothing at all. It is possible that it has crashed; please check whether there are crashing bugs in this application. *** Exception NoMethodError in PhusionPassenger::Rack::ApplicationSpawner (undefined method `call' for nil:NilClass) (process 25574):
I’ve tried older versions of passenger also but get the same error.
- Ubuntu 10.4
- Apache 2.2.14
- Ruby 1.9.2-p0
- Passenger 2.2.15
Have you checked to ensure that all of the config files used by your application are populated? (related)
