TError always unknown

Hello, When we use the TError type from codegen, the type is always unknown. How to have the payload or message of all the 400s and 500s errors typed ? Thanks

To Reproduce Steps to reproduce the behavior: npx --package @7nohe/openapi-react-query-codegen openapi-rq -i https://petstore.swagger.io/v2/swagger.json -o src/generated

Expected behavior I need to have the content or message of all the 400s and 500s errors.

Facing the same issue, I don't know how to use error message in my returned data with the onError method.

My openapi.yml has definitions for error objects returned on 400 error code and these are picked up in the types.gen.ts file but I don't see how to use them in my mutate hooks.

From v2, TError is now typed.

export const useFindPets = <
  TData = Common.FindPetsDefaultResponse,
  TError = FindPetsError,
  TQueryKey extends Array<unknown> = unknown[],
>(
  clientOptions: Options<FindPetsData, true> = {},
  queryKey?: TQueryKey,
  options?: Omit<UseQueryOptions<TData, TError>, "queryKey" | "queryFn">,
) =>
  useQuery<TData, TError>({
    queryKey: Common.UseFindPetsKeyFn(clientOptions, queryKey),
    queryFn: () =>
      findPets({ ...clientOptions }).then(
        (response) => response.data as TData,
      ) as TData,
    ...options,
  });
