Processing data package fails with descriptor validation errors

[PiDelport]

Context: I'm in the process of adapting ~150 civic data sets to datahub.io: the following data package is a test upload.

How to reproduce

The following data package validates with data validate and uploads successfully with data push:

• https://datahub.io/pi/22t8-gvzh/v/1

However, processing it fails:

ERROR: Data Package validation error: Descriptor validation error: {'name': '__placeholder__', 'path': '_', 'profile': 'data-resource'} is not valid under any of the given schemas at "resources/0" in descriptor and at "properties/resources/items/oneOf" in profile

ERROR: Data Package validation error: Descriptor validation error: 'data-resource' is not one of ['tabular-data-resource'] at "resources/0/profile" in descriptor and at "properties/resources/items/properties/profile/enum" in profile

The datapackage.json was inferred from the CSV with Package.infer, and then enriched with additional metadata fields:

Expected behavior

Processing should succeed?
