When trying to execute the following:
3scale-cli import swagger -f json_vcc.json

I received the following error:```

@lucamaf this issue comes because the property basePath is not defined in the spec.
I would recommend to define it basePath even if it's just / and it will work.

[lucamaf]

is it possible to catch this specific error and provide the indication in the error stack?

there are many reasons why this could throw a 422 error.

in the last version the 422 undefined is replaced with 422 <details of the error
