Error log is empty.

Question

Hi,

I have 400 http answer. I see it on access log /home/USER/logs/frontend/access_WEBSITE.log But error log is empty /home/USER/logs/frontend/error_WEBSITE.log

Where can I find description of error?

Answer 1

That just means that your application is returning a 400 HTTP Response code but isn't providing more information (so, there's nothing interesting to log).

You'll need to trace the request through your application manually and determine how far it's getting. If you're using python, you can do something like this to get a python prompt at an opportune time:

import code
code.interact(local=locals())

This is a good choice if you want to explore the execution state but don't need a full-fledged pdb session. Also see the mod_wsgi debugging techniques.
