Trying to do the Google php "Bookshelf" tutorial, and everything works fine locally. But when I deploy it to my Google Cloud Platform and try to browse to it, I get a "404 Not Found / nginx" error.
Here is the log file from the deployment:

Please forgive the enormous block of code, but I don't know what's important in it. My understanding is that with a basic cloud app, credentials are not a big thing. Any idea why I'm getting the 404 Not Found / nginx error?
I ran into a similar error message once or twice while writing an app based on the same tutorial series, though I'm using Node.js.
For me, my app appeared to have been crashing because of exceptions (which I fixed in a few cases), and also what appears to be a problem with connect-memcache (that one I'm still trying to debug...).
I figured out this much by commenting out huge sections of code, making an extremely simple page that I would be sure would show up, then gradually un-commenting code and re-deploying to see if that uncommented code broke anything.
