Question

I am having trouble running a Backend from a Task Queue in Google app engine. It looks like I have everything set up correctly according to the documentation, but when I try to run the Task the Backend is not started, and I don’t get much back from the logs other than a 404 error. It’s probably something small that I’m missing but I have been working on it for a couple days now and just can’t figure out what it is.

Here is what my Backends.yaml looks like

backends:
- name: batchloader
  instances: 1
  options: dynamic
  start: batchcron.app

Here is the handler in app.yaml

- url: /crons/batch
  script: batchcron.app
  login: admin

Here is my taskqueue call to the backend

taskqueue.add(url='/crons/batch', target='batchloader')

What am I missing here? Any help would be greatly appreciated. Thanks!

Quick update to this issue. It was a couple of small things that I overlooked. Someone1 was right as I did not have the backends started in the admin council. I thought since they were dynamic and would start and stop themselves.So that is fixed now. The other was that in my call to crons/batch I was using the default post method, but the function I was calling was a get. So I just changed that function and everything worked.

Thanks for the help and suggestions!
