Description

I have generated html2 documentation. But index.html does not include requestBody.
I need to know, how to add the requestBody in the documentation?

Command line used for generation

openapi-generator generate -i swagger/swagger.yaml -g html2 -o docs/

Suggest a fix/enhancement

Generator needs to support for the body parameters and response examples to be included in index.html

Adding to the issue specified:-
if the Request body accepts List as a parameter.

Open API shown
[undefined]

But if the Request Body accepts an object, it works fine.
