Description

Makes uncompilable haskell

Installed openapi-generator from Arch repo.

Entered generated directory
stack build

/home/ad/TIKO/openapi/lib/IPRLBSP/Model.hs:465:43: error:
    Not in scope: type constructor or class ‘AnyType’
    |

I can't find "AnyType" in Hoogle or the generated codebase.

Suggest a fix

Use a type that exists instead of AnyType

Run openapi-generator with IP_RL_BSP_API-3.0.yaml and -g haskell-http-client, then inspect the generated Model.hs around line 465 where AnyType is referenced. Compare that field with the generated model types and rebuild with stack; done means the generated Haskell client compiles without an undefined AnyType.
