Error uploading Google App Engine Application

Question

I am using a normal command to upload my application in Google App Engine (Python 2.7, SDK 1.8.9):

appcfg.py --oauth2 update .

But after a refactoring in my project there is an error in a regular expression for app.yaml (here is the code)

The error is:

02:00 AM Application: sandengine; version: dev
02:00 AM Host: appengine.google.com
02:00 AM Starting update of app: sandengine, version: dev
02:00 AM Getting current resource limits.

Answer 1

Its pretty easy to figure out what file of your app.yaml is the problem by putting a print here.

/home/nburn42/Apps/google_appengine/google/appengine/tools/appcfg.py

line 315

It is maybe a bit overkill but it will definitely get you unstuck.

Answer 2

dev is a reserved keyword. Change the version and instead of dev use a number or a lowercase string.

It Worked for me

Answer 3

It is a regular expression error, where in upload: you can't use \1 or \2

Here is the fix: https://github.com/coto/gae-boilerplate/commit/7fbcba2cb217f8ccd8ced7bfe634b4aceaf616c6

Answer 4

Instead of "dev" as the version number, try putting in an actual number :)
