Google App Engine remote_api returns 404 using remote_api_shell.py

[Andrew Free]

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 suddenly cant connect.

My friend who is also working on the project with me tried on his machine and got the same error. It was working fine for the past couple months. I'm also using the remote_api_shell so it can't be something in my code?

My app.yaml has

builtins:

- remote_api: on

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.

Probably the SDK path is invalid. If so try this.

Open the tool,

Edit --> Preferences --> Appengine SDK: C:\Program Files (x86)\Google\google_appengine

and update your application writing this line in cmd,

appcfg.py update your_apps_path

I'm on OS X but the path is correct. Again I'm getting logs on the server side so something is working to a degree. Tried updating/deploying it and still having the same issue.

"GET /_ah/remote_api" 404 130 - "Google-remote_api"

It looks like App Engine doesn't have anything mapped to the /_ah/remote_api path. Which is clearly incorrect; the remote_api builtin should be automatically mapping itself to that path. You might want to file a production issue at https://code.google.com/p/googleappengine/issues/list 

With that said, there is something else you can try. See if you can force the mapping to remote api by inserting the following into the handlers section:

- url: /_ah/remote_api

  script: google.appengine.ext.remote_api.handler.application

  login: admin

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.

[Andrew Free]

I use the deploy built into that app engine launcher that comes with the SDK on osx. I don't know if that is the same thing. I read about doing a normal appcfg update to fix this but it doesn't seem to be the problem for me.

I ran into this problem today too. Have you solved your problem?  Hope you can see this and drop a line about your solution. Thank you!

[Andrew Free]

Try uploading/deploying your code sometimes it just needs to be pushed to google. I’m not sure how I ended up solving this exactly. I have had lots of issues with the remote API.
