OperationalError: unable to open database file

[vivpuri]

I am trying out the data download using remote_api and getting the
following error:

*******************************************************
No descending index on __key__, performing serial download
......................................................................
[ERROR ] [Thread-11] ExportP

I am using the following command:
bulkloader.py --dump --kind=<kind> --url=http://<appname>.appspot.com/
remote_api --filename=<data-filename> <app-directory>

Any ideas how this issue can be resolved?

Thanks

Hi,

Try adding the --clear_datastore flag, to start with a fresh datastore.

Hi,

This is not an error - those warnings are normal when running with clear_datastore. Have you tried accessing your app?
