Invalid sample data

When running "python tools/sample_data.py", I get this error:
curl -i -X POST -H 'Content-Type: application/json' -H 'Accept: application/json' -d '{"capacities": [{"unit": "count", "value": "1", "name": "cpu"}, {"unit": "GB", "value": "1.7", "name": "memory"}, {"unit": "GB", "value": "160", "name": "storage"}], "name": "m1.small"}' http://localhost:6385/v1/flavors
Request returned failure/redirect status.

It might be that flavors creation in sample_data is obsolete (flavors are not top-level resource anymore).
