Describe the bug you're encountering

When a schema does not have a type in a parameter, it will crash SwaggerUI.

To reproduce...

Copy above YAML to editor.swagger.io:
Then open the GET operation in swaggerUi.

Result: Console crashes where setDefaultValue cannot perform a toJS() on a null.

This can put the spec in an unusable state.
