swagger.json handle properties under 'allOf'

[MrBasque]

Hi, thanks for this nice package. However, we are currently unable to generate a form due to the following error:

node_modules\@verizonconnect\ngx-form-generator\dist\generator-lib.js:59
  const fields = Object.keys(definition.properties);
                        ^
TypeError: Cannot convert undefined or null to object

Our swagger.json contains several definitions that are structured like this:

"definitions":{
  "Trade": {
    "allOf": [{
        "$ref": "#/definitions/RootEntity"
      },
      {
        "type": "object",
        "properties": {
         "companyName": {
            "type": "string"
          },
          ....
        }
      }
    ]
  },
....
}

We did nothing special to the swagger configuration that I know of. the generator-lib.js though, searches for "properties" as a direct child property which it cannot find in this case, because the properties are within an child under the "allOf" property.

anything we can do to resolve this?
