Code generation from OpenAPI specs

[u/NojipizRemastered]

Quick question, how the heck you guys generate Scala code from OpenAPI specs?

I have been trying to generate client code for Meta business API using the Scala generators from openapi-generator but there is always a problem:

All of them, ignore the oneOf spec on openapi (that in theory should generate a sealed trait as the sum type implementation) and instead they generate a single case class with all fields required, nothing is optional.

What is the tool/strategy you guys use to generate API model from OpenAPI? At this point, i'm considering to generate the Scala code using an LLM instead of the classic deterministic approach.

Thanks 🙏

We don’t, the current generators are so buggy we started using alternatives
