TypeScript Error: Cannot invoke an expression whose type lacks a call signature. Type 'Something' has no compatible call signatures

Question

过去几天我一直被这个 typescript 错误困扰。

Cannot invoke an expression whose type lacks a call signature. Type '(<TResult1 = ApiResponse, TResult2 = never>(onfulfilled?: ((value: ApiResponse) => TResult1 | PromiseLike<TResult1>) | null | undefined, onrejected?: ((reason: any) => TResult2 | PromiseLike<...>) | null | undefined) => Promise<...>) | (<TResult1 = void, TResult2 = never>(onfulfilled?: ((va...' has no compatible call signatures.

代码：

const getDetailsPromise = myCode
              ? storeApi.getDetails(params, [myCode])
              : Promise.resolve();
return getDetailsPromise.then(
              (result: ApiResponse | void) => {
                .......Some logic
                .......Some logic
                return Promise.resolve<
                  [MethodResponse, ResponseHeaders]
                >([ShippingResponse, response.headers]);
              }
            );

storeApi.js

getDetails(
        requestParams: RequestParams,
        myCode: string[]
    ): Promise<ApiResponse> { 
        .......Some logic
        .......Some logic
    }

这里getDetailsPromise returns要么是Promise，要么是Promise。如果值存在，我们还期望 myCode 类型为字符串。我在尝试构建应用程序时遇到上述错误。有人可以 help/guide 我来解决这个问题吗？任何帮助将不胜感激。

提前致谢！

Answer 1

感谢Anatoly。我将包装器中的 return 类型更改为具有联合类型的 Promise，而不是 Promise-d 类型的联合。
