Google App Engine remote_api returns 404 using remote_api_shell.py

Question

I'm using googles built in tool for connecting to the remote api so I don't even have info in my client or app.yaml I could change. I have no idea why I suddenely cant connect.

[ rever ~/Documents/buybottmerge/buybott-gae ] remote_api_shell.py -s myappname.appspot.com

urllib2.HTTPError: HTTP Error 404: Not Found

I can see the errors on my logs in the dashboard as well. So something is working well enough for it to get that far before failing.

Hmm, I would double check app.yaml and redeploy. If that fails then raise a production issue. (I use remote api all the time and have never had that problem except when forgetting to enable remote_api in builtins, or in the old days forgetting to map a remote_api handler in app.yaml — Tim Hoffman

@TimHoffman Yea I tried all that, still fails. I just decided to raise an issue here. I can't really work on my project until this gets resolved :/ — Andrew

I know this is a little late, but are you using the git push-to-deploy feature on your app?

I've found that the "builtins" defined in app.yaml do not work after a push-to-deploy (they return 404s) but doing a normal appcfg update makes them work again.

I experienced these 404 failures after push-deploys with both remote_api and deferred.

If you are like me who followed this doc and used "buildins", I figured out that the error was because of a typo in the document.

/remote_api ==> /_ah/remote_api

for me the problem was that I started the script with wrong project.appspot.com name. Be careful
also the project should be deployed first with:

builtins:

remote_api: on

in app.yaml
