Ok, this one was a beating. For my wedding website I am using Google App Engine, a cloud PaaS system. The application is written in Groovy on Gaelyk. So far everything has been great, until yesterday.

While attempting to deploy my application I started getting an error like this:

Unable to update:java.io.IOException: 
Error posting to URL: https://appengine.google.com/api/appversion/deploy?app_id=adammaryannewedding&version=4&400 Bad 
RequestClient Error (400)
The request is invalid for an unspecified reason.

This infuriating error message is so maddening because it tells you absolutely nothing about what could be going wrong. After a lot of searching I found some old forum entries talking about getting this error if you have too many files to upload. How many is too many? Turns out that the hard limit is 1,000 files.

I understand limits. Even though I think 1,000 is a bit light, throw me a bone and at least let me KNOW that this was the problem!

Oh, and feel free to visit my wedding site at www.adamandmaryannewedding.com. Cheers!
