Referencing Domain document from OpenAPI 3.0 document

Hi - I have a domain document at 

https://app.swaggerhub.com/domains/UPennISC/pennant_domain/1.0.0

With a 'definitions:' section and a 'commonResponesStatusStructure' structure.

 

I'm trying to reference it in my OpenAPI 3.0 document like this:

responses:
   '200':
     description: Response from the web service.
     content:
         application/json:
           schema:
             $ref:                    'https://app.swaggerhub.com/domains/UPennISC/pennant_domain/1.0.0#/definitions/commonResponesStatusStructure'

 

I get "Could not resolve reference: Could not resolve pointer: /definitions/commonResponesStatusStructure does not exist in document"

What am I doing wrong? This works fine for me in a 2.0 api document but I'm not sure how to make it work in 3.0.  I was told this should work.  Feel like I'm just missing one thing. I've tried to google my way to a solution and I can't find one.  Thanks - Tim
