Post requestBody not showing/generating

I'm trying to add request body here for my post endpoint, I cannot, I have tried requestBody property and nothing.
As seen in the picture I've been able to add it manually in the json output but not from the yml config file

```yml
endpoints:
createPerson:
summary: Crear personaje
description: Crea un personaje nuevo en la BD.
requestBody:
description: "Body param"
requestModels:
application/json: RequestObject
```

Basically this object is not being generated I have to add it manually for it to work


No source file, test, or entry point is named. Start by tracing how the endpoints YAML configuration maps to the generated JSON, focusing on the requestBody and requestModels fields; done when the configured request body appears in the generated OpenAPI output without manual edits.
