我最近一直在尝试熟悉ReactQuery和TypeScript，并基于useMutation的签名：
function useMutation<TData = unknown, TError = unknown, TVariables = void, TContext = unknown>个
我的理解是这样的：

• TData是调用mutate时返回的结果的类型。
• TError是错误时的错误响应类型。
• TVariables是传递给mutate的参数的类型

我目前正在尝试创建一个钩子，它将发布到一个端点，如果成功，将返回一个204 No Content响应，所以我尝试了这个：

const { mutate, ...actionResults } = useMutation<
    AxiosResponse<null>, // <-- I put null here because I expect a 204 no content response
    AxiosError<ErrorResponseType>,
    ParamsInterface
  >(
    ({param1, param2}: ParamsInterface) => { // Having null above gives me an error on this line, see details below.
      return requestor(Rest.sendRequest(param1, param2))
    },
    {
      onSuccess: () => {
        // do something on success
      },
      onError: (error) => {
        // do something on error
      },
    },
  )

字符串
上面评论中提到的错误是：

Overload 1 of 4, '(mutationFn: MutationFunction<AxiosResponse<null>, ParamsInterface>, options?: Omit<UseMutationOptions<AxiosResponse<null>, AxiosError<ErrorResponseType>, ParamsInterface, unknown>, "mutationFn">): UseMutationResult<...>', gave the following error.
     Argument of type '({ param1, param2 }: ParamsInterface) => AxiosPromise<object>' is not assignable to parameter of type 'MutationFunction<AxiosResponse<null>, ParamsInterface>'.
       Call signature return types 'AxiosPromise<object>' and 'Promise<AxiosResponse<null>>' are incompatible.
         The types of 'then' are incompatible between these types.
           Type '<TResult1 = AxiosResponse<object>, TResult2 = never>(onfulfilled?: (value: AxiosResponse<object>) => TResult1 | PromiseLike<TResult1>, onrejected?: (reason: any) => TResult2 | PromiseLike<...>) => Promise<...>' is not assignable to type '<TResult1 = AxiosResponse<null>, TResult2 = never>(onfulfilled?: (value: AxiosResponse<null>) => TResult1 | PromiseLike<TResult1>, onrejected?: (reason: any) => TResult2 | PromiseLike<...>) => Promise<...>'.
             Types of parameters 'onfulfilled' and 'onfulfilled' are incompatible.
               Types of parameters 'value' and 'value' are incompatible.

                   Type 'object' is not assignable to type 'null'.

型
上面的错误通过保留AxiosResponse未类型化而消失，我假设它保留默认的any类型。
为什么响应（TData）中定义的类型会影响mutate（TVariables）的参数中预期的类型？至少我现在是这么看的，也许我没有正确理解错误消息。
任何帮助都是赞赏的，谢谢！
