Describe the bug you're encountering

Unable to render query string parameter when using 'content' instead of schema. I'm using 'content' because my query string is a json string, as stated in the example.

To reproduce...

Steps to reproduce the behavior:

1. Use 'content' as stated in https://swagger.io/docs/specification/describing-parameters/

      parameters:
        - in: query
          name: filter
          content:
            application/json:  # <---- media type indicates how to serialize / deserialize the parameter content
              schema:
                type: object
                properties:
                  type:
                    type: string
                  color:
                    type: string

(complete yaml above)
2. See error when rendering in swagger UI: 😱 Could not render ParameterRow, see the console.
3. Console output:
root-injects.js:95 TypeError: Cannot read property 'get' of undefined
at t.value (parameter-row.jsx:145)
at t.render (root-injects.js:93)
at s._renderValidatedComponentWithoutOwnerOrContext (ReactCompositeComponent.js:796)
at s._renderValidatedComponent (ReactCompositeComponent.js:819)
at s.performInitialMount (ReactCompositeComponent.js:359)
at s.mountComponent (ReactCompositeComponent.js:255)
at Object.mountComponent (ReactReconciler.js:43)
at X.mountChildren (ReactMultiChild.js:234)
at X._createInitialChildren (ReactDOMComponent.js:701)
at X.mountComponent (ReactDOMComponent.js:520)

Expected behavior

Input is rendered

Closing as a duplicate of #4442 😄

The solution to the problem : "😱 Could not render this component, see the console." in Swagger Open API 3 can be resolved by following the link: https://swagger.io/docs/specification/describing-parameters/
