Javascript 如何捕获在调用堆栈之外发生的aws sdk错误？ 形势

我正在使用aws sdk与S3 bucket进行交互

如果我没有设置正确的凭据，sdk会相应地抱怨。然而，它的投诉方法是抛出到调用堆栈之外的错误。我希望能够捕捉到错误并优雅地处理它

问题 下面是导致问题的一个小脚本

import { S3 } from 'aws-sdk';
try {
  const s3 = new S3();
  s3.createPresignedPost({}, (err, data) => {
    console.log('sup dog');
  });
} catch (err: Error) {
  console.log('KABOOM!');
}

我希望它能够捕获由

s3.createPresignedPost引发的任何错误并触发捕获，但实际发生的是
sup dog
被发布，然后节点崩溃，堆栈跟踪指向aws sdk

sup dog

      ^

问题
当然，这里的解决方案是使用凭据正确配置aws sdk，但我希望通过捕获错误并防止硬崩溃来优雅地处理尚未发生的情况

如何使用
createPresignedPost的回调模式而不冒系统崩溃的风险？
我创建了这个lambda请求：

const AWS = require('aws-sdk');

const s3 = new AWS.S3();


exports.handler = async (event, context) => {
    //console.log('Received event:', JSON.stringify(event, null, 2));

    let body;
    let statusCode = '200';
    const headers = {
        'Content-Type': 'application/json',
    };
    var params = {
      Bucket: 'bucketname',
      Fields: {
        key: 'example.pdf'
      }
    };
    try {
        s3.createPresignedPost(params, (err, data) => {
            body = "successfully";
        });
    } catch (err) {
        statusCode = '400';
        body = err.message;
    } finally {
        body = JSON.stringify(body);
    }

    return {
        statusCode,
        body,
        headers,
    };
};

对于测试成功案例，请按原样运行代码。对于测试错误注释，请使用bucket或key中的一个key参数。它将抛出error和catch

Response:
{
  "statusCode": "400",
  "body": "\"Unable to create a POST object policy without a bucket, region, and credentials\"",
  "headers": {
    "Content-Type": "application/json"
  }
}

结果是，我发布了一个被合并的

所以，这个问题的答案是不可能捕捉到这个错误…但现在你不必捕捉到
