即使资产目录看起来正常，AWS Lambda Stack 也无法找到资产错误

Question

目录图像 我试图部署一个包含 lambda 函数的 lambda 堆栈。该函数将运行的代码位于源文件夹下的 services 文件夹中。即使我的文件目录在 lambda 函数中似乎是正确的，我也会遇到找不到资产错误。有谁知道我错过了什么？

import { Stack, StackProps } from "aws-cdk-lib";
import { Construct } from "constructs";
import {
  Code,
  Function as LambdaFunction,
  Runtime,
} from "aws-cdk-lib/aws-lambda";
import { join } from "path";

export class LambdaStack extends Stack {
  constructor(scope: Construct, id: string, props?: StackProps) {
    super(scope, id, props);

    new LambdaFunction(this, "getBooksLambda", {
      runtime: Runtime.NODEJS_18_X,
      handler: "getBooks.main",
      code: Code.fromAsset(join(__dirname, "..", "..", "services", "getBooks")),
    });
  }
}

exports.main = async function(event, context) {
    return {
        statusCode: 200,
        body: JSON.stringify({
            message: "Hello from Lambda"
        })
    }
}

Error: Cannot find asset at C:\Users\User\Documents\Bookeroo\bookeroo-cdk\src\services\getBooks

我只是尝试运行它，希望 cdk 合成器不会抛出错误。我还尝试移动 getBooks 文件并将 .js 添加到目录末尾。他们都没有工作

根据docs，

Code.fromAsset

接受

Either a directory with the Lambda code bundle or a .zip file.

将您传递的路径更改为包含资产的文件夹（即删除

"getBooks"

）
