Question

I follow this steps from API Google App Engine: https://developers.google.com/appengine/docs/adminconsole/datastoreadmin#Copying_Entities_to_Another_Application

1. With Python SDK, I deploy the datastore_admin app: appcfg.py -A APPID update DIRECTORYOFDATASTOREADMINAPP
2. In the Dashboard, I select the entities and press Copy to Another App entering the remote endpoint: https://ANHORTHERAPPID.appspot.com/_ah/remote_api

I get the following error: “There was a problem kicking off the jobs. The error was: Fetch to https://ANHORTHERAPPID.appspot.com/_ah/remote_api failed with status 404″

Any help? I’m totally lost 🙁

Answer 1

Solved:

1. You must be owner (role) in both applications (origin and destination)
2. You must edit the datastore_admin app (download it at first link in my post) and edit the files:
   • app.yaml: ID of destination app
   • appengine_config.py: ID of origin app
3. Deploy the datastore_admin app in both apps:
   • appcfg.py -A APPIDORIGIN update DIRECTORYOFDATASTOREADMINAPP
   • appcfg.py -A APPIDDESTINATION update DIRECTORYOFDATASTOREADMINAPP
