I have the same issue. Generating for Javascript. AnyOf file which is required in the model just doesn’t exist. Looks like the generator does not generate it. No errors and warnings during the generation process.

5.0.0-beta3

Doesn’t solves the problem

Same bug persists when generating java client with version 5.4

I’m running into the same issues using the Gradle plugin version 5.4.0 and the spring server generator. Anybody found a workaround for this issues perhaps?

After stumbling on this issue last year, I decided to create a new generator that would generate complex types (inline or not). It has been working great for me, you can find it here: https://github.com/Embraser01/typoas Edit: It only applies to TS/JS clients, not other languages

P.S.: The main goal here isn’t to advertise my project, just to propose a solution to this issue. If wanted, I can remove the link to the project and let users find it through my profile

I’m seeing this in the latest using the typescript-fetch generator.

It improperly returns invalid javascript that points to a class, a typescript single pipe, and a function that isn’t actually defined.

'item': Item | numberToJSON(value.itemId),
