在过去的几天里，我一直被这个打字错误所困扰。

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
    }

在这里，getDetailsPromise返回许诺或承诺。此外，如果值存在，我们期望myCode类型为string。在构建应用程序时，我会得到上面提到的错误。有人能帮我解决这个问题吗？任何帮助都会很感激的。
