Brief Introduction:
We are facing issues while generating the sphinx documentation while using openAPI 3.0.1 yml template files .
But it works successful with the Swagger 2.0 template.

Ask:
Can you please confirm if sphinx supports OpenAPI 3.01 templates for documentation?

Problem Statement :
Specifically, we are facing issues for following parameters in documentation.
a) Request Json Parameters
b) Response Json Parameters

As per below example of Open API 3.01 template it expects

( schema property is child of content)

where as in Swagger 2.0 the structure looks like this.

if we use the Swagger 2.0 yml to generate the HTML documentation then I successfully generates the Request JSON Parameter and Response JSON Parameters as below.

where as with former with openAPI 3.0.1 template it failed to load these request Json parameter and response Json Parameters

You can refer any sample open API 3.0.1 template from internet to reproduce this issue.

Really appreciate your prompt support.
