Openapi Generator Reproducer

TL;DR

1. Run the backend with

   ./mvnw clean quarkus:dev

2. Check that uploading works by uploading this README.md for example:

   curl -X POST \
     http://localhost:8080/api/something/upload \
     -H "Content-Type: multipart/form-data" \
     -F "uploadFile=@README.md"

3. In the frontend "project" run

   rm -rf ./src/api
   npm run openapi:codegen

   (don't forget npm i)

4. You should now have a generated SomethingApiApi (no naming settings) that contains an objectToJSON function that is not declared anywhere

About

I think Openapi generator has a bug when dealing with Java/Kotlin/JVM in general (?) FileUpload types. This repo contains a very slim Quarkus/Kotlin project that exposes one multiform upload API.

When generating code (for a Svelte project) with typescript-fetch, there is a function objectToJSON that is not declared anywhere. The generated code therefore does not work.

You can check out openapi.json and Swagger, etc from http://localhost:8080/q/dev-ui when running the backend.
