TypeError: Cannot read property '$ref' of null

When trying to use this for the first time, I get the following. I can provide more info if necessary:

node index.js
/Users/mikecataldo/code/swaggerTT/node_modules/json-schema-faker/lib/jsf.js:76
      throw e;
      ^

hmm, it seems it doesn't deref your swagger spec. Can you post the swagger spec you are using?

[mccataldo]

It's a very big and complex spec. Let me try with a simpler spec with refs and see what happens.

[Remco75]

ok, let me know how it goes.
The issue you have with de-reffing your spec so that we have all the data we need at runtime.
So check if your json -refs are complete -> if not it will fail.
Also your spec needs to be valid: there's tools to check this online (but I don't think that is the issue you are having at this point)
