How to express an "any" type for a property.

I’m trying to work out how to express a property that’s an “any” type using swagger and autorest. What I found through searching the web is that in swagger 2.0 you need to simply remove the “type” for a property to say its an any which if you look at my value property you’ll see I’ve done:

"CardAction": {
      "description": "A clickable action",
      "type": "object",
      "properties": {
        "type": {
          "$ref": "#/definitions/ActionTypes",
          "description": "The type of action implemented by this button"
        },
        "title": {
          "description": "Text description which appears on the button",
          "type": "string"
        },
        "image": {
          "description": "Image URL which will appear on the button, next to text label",
          "type": "string"
        },
        "text": {
          "description": "Text for this action",
          "type": "string"
        },
        "displayText": {
          "description": "(Optional) text to display in the chat feed if the button is clicked",
          "type": "string"
        },
        "value": {
          "description": "Supplementary parameter for action. Content of this property depends on the ActionType"
        }
      }
    }

But when I run this through autorest using the --typescript switch get a mapping to type object in the generated mapper.ts file which causes the generated client to fail the outbound serialization for non-object values:

export const CardAction = {
  required: false,
  serializedName: 'CardAction',
  type: {
    name: 'Composite',
    className: 'CardAction',
    modelProperties: {
      type: {
        required: false,
        serializedName: 'type',
        type: {
          name: 'String'
        }
      },
      title: {
        required: false,
        serializedName: 'title',
        type: {
          name: 'String'
        }
      },
      image: {
        required: false,
        serializedName: 'image',
        type: {
          name: 'String'
        }
      },
      text: {
        required: false,
        serializedName: 'text',
        type: {
          name: 'String'
        }
      },
      displayText: {
        required: false,
        serializedName: 'displayText',
        type: {
          name: 'String'
        }
      },
      value: {
        required: false,
        serializedName: 'value',
        type: {
          name: 'Object'
        }
      }
    }
  }
};

Is this just a bug in the typescript plugin?

Awesome! Thanks @olydis. We already have a post processing script to do other similar fixups so I should be good. Thanks again for the quick turn around 😃

@Stevenic The legendary @amarzavery has spoken: He’ll update ms-rest-js (should be tagged here soon) to allow you to write

      value: {
        required: false,
        serializedName: 'value',
        type: {
          name: 'Any'    // <======= new thing here
        }
      }

Long term, this will be what AutoRest generates for your Swagger, but well, you know about the issue tracking that 😉 Until then, I’ll happily assist you to hack something into your generation command that’ll replace Object with Any for that property, in case manually changing that is not feasible (e.g. if you expect to regen very frequently, which would always override your fix…)
