oneOf generates a wrong zod definition

[Michael]

When we create a zod client via openapi-zod-client spec/openapi.json -o src/validation.ts for the following openapi.json, it generates a wrong zod definition (const TestObject = z.union([z.unknown(), z.unknown()])).

Using oneOf in the openapi.json leads to that error.
