Error with the exported NodeJS-server version

Description

Hello!

I've been facing an issue with the exported version of my API. I export it to nodejs-server and I run on another server so my business partners can check the documentation.

The problem that i'm facing occurs with array objects that are not showing their nested properties. This behavior only occurs in the exported version. While I'm edting it on swaggerhub or swagger editor it properly appears, as shown below:

On my API documentation website it is shown like this:

It was working sometime ago, i've been trying to fix it but wasn't successful. I don't know if something changed that I need to change my code or there's a bug out there.

Swagger-codegen version

I'm using SwaggerHub OAS 2.0, I'm kinda new in this area, don't if that answers this topic (:

Start with the simplified Swagger definition in the linked Gist and reproduce the nodejs-server export, comparing its rendered array objects with the SwaggerHub or Swagger Editor view. Trace the generated documentation output and confirm that nested properties in array objects are displayed consistently in the exported version.
