Unable to import from Swagger

Hi!, 

I want to try SoapUI out at work to see if it could make our life easier (I'm a QA and test a ton of our APIs regularly) but I'm running into a problem when trying to import one of our APIs definition from swagger. 

Basically what I do is I create an empty project then right click on it -> import from swagger -> I leave 'Definition Type' set to 'Resource Listing' and in the 'Swagger Definition' field point it to ${ourAppHost}/v2/api-docs.json. I click accept then it asks me for username/password (our API needs authentication) but then I get an error message saying it can't find something. 

The error message says this: 

groovy.lang.MissingPropertyException: No such property: path for class: com.smartbear.swagger.Swagger2Importer

And the logs show this: 

2016-02-15 23:22:33,314 ERROR [SoapUI] An error occurred [No such property: path for class: com.smartbear.swagger.Swagger2Importer], see error log for details

I thought there might be something that's not correctly configured with my installation (I'm using SoapUI free version 5.2.1) but then I tried to load a public API in the same way (this one) and it loaded up correctly and imported all the endpoints. 

In my app we don't have a /v2/swagger.json like in the public api that works but we do have it in /v2/api-docs.json and if I go there in a browser I get this (the host is masked since it is a private app): 

which looks pretty similar to the one in the link above that works. 

Any idea what I might be doing wrong? Is there anything I'm missing?. 

Thanks!.
