Maybe duplicated https://github.com/api-platform/client-generator/issues/198

This feature is experimental and I hadn't a chance to test it by myself yet... There are chances it is broken. I strongly recommended using the Hydra support for now.

Hi, @dunglas. Thank you for the very fast reply. The main problem for me that I want to use generators with some OpenAPI v3 enabled api. I haven't any chance in this point, because only api-platform exposed Hydra-enabled api.

Getting the same here trying to get client-generator to work with my FastAPI projects.

Is there any chance someone will have a look ?

Best regards.

OpenAPI 3 support has been greatly improved in the client generator (and the underlying library) since https://github.com/api-platform/api-doc-parser/pull/108. There should no be major issue now.
