Hi @Ken Yee
This information is not available yet. I’m adding it in the candidates for future improvements.
Regarding the OpenApi generators, we use the java one ourselves and submitted a few PRs to the OpenApi generator project to properly generate the query params, deal with ‘exploded’ parameters, etc.
So I’m not surprised generators for other languages are buggy as well. If you fancy submitting a PR to them, that would be nice 🙂
