Error while importing WADL (ns2 namespaced): TypeError: Cannot read property 'push' of undefined

Question

I'm trying to import the most recent Data Center WADL into Postman, but it fails.

Using my own from rest/api/2/application.wadl also fails.

APIMatic is similarly confounded:

* Endpoint setPreference has a response definition with invalid status code .
* Endpoint removePreference has a response definition with invalid status code .

* One or more elements in the API specification has a missing description field.

This also happens when using APImatic or similar converter. Makes no difference whether I use the wadl from the app or from Atlassian.
