以下代码随机失败：

执行上下文被破坏，很可能是因为导航。

这是为什么？任何解决方法？

我使用 puppeteer 版本 1.19.0

注意：我正在寻找一种通用解决方案，它允许导航到具有重定向的页面和没有重定向的页面。

const puppeteer = require("puppeteer");

(async () => {
  const browser = await puppeteer.launch();

  try {
    const page = await browser.newPage();

    await page.setCacheEnabled(false);

    const response = await page.goto("https://docs.cypress.io/", {
      waitUntil: "networkidle0",
      timeout: 60000
    });

    const pageUrls = await page.evaluate(() => {
      const links = Array.from(document.querySelectorAll("a"));

      return links.map(link => link.href);
    });

    console.log({ pageUrls });
  } catch (error) {
    console.log(error.message);
  }

  await browser.close();
})();

尝试运行无服务器时收到以下警告。

找不到满足声明 'opt:stage' 的有效选项。下面是我的 serverless.yml 文件

我正在构建一个无服务器应用程序，它在资源中定义了一个 SQS 队列，如下所示：

resources:
  Resources:
    TheQueue:
      Type: "AWS:SQS:Queue"
      Properties:
        QueueName: "TheQueue"

我想从其中一个函数中向这个队列发送消息。如何从函数内部访问 URL？我想把它放在这里：

const params = {
    MessageBody: 'message body here',
    QueueUrl: 'WHATS_THE_URL_HERE',
    DelaySeconds: 5
};

我正在运行我的 nodejs 代码并安装了无服务器（npm i -g serverless）但是在使用命令运行它时sls offline start --CacheInvalidations我收到错误：-

未找到无服务器命令“离线”。您指的是 “config” 吗? 运行“无服务器帮助”以获取所有可用命令的列表。

今天早上，我项目的无服务器部署开始失败。我没有更改代码中的任何内容，最后一次成功部署大约是在一周前。

这是部署日志：

谁能帮我找出问题所在吗？

我正在我的无服务器 yml 中导入此 cloudformation 资源。这是我的功能配置：

Resources:
  eventHandler:
    Type: AWS::Serverless::Function
    Properties:
      CodeUri: eventLambda/
      Handler: dist/app.eventHandler
      Runtime: nodejs12.x
      FunctionName: eventHandler

这是我引用它的地方：

eventSourceRule:
    Type: 'AWS::Events::Rule'
    Properties:
      Name: eventSourceRule
      EventBusName: omnibus-${self:custom.stage}
      EventPattern: |
        {
          "source": ["op.api"]
        }
      RetryPolicy:
        MaximumRetryAttempts: 5
        MaximumEventAgeInSeconds: 900
      DeadLetterConfig:
        Type: SQS
        QueueLogicalId: EBRuleDLQ
      Targets:
        - Arn:
            Fn::GetAtt:
              - 'EventHandlerLambdaFunction'
              - 'Arn'
          Id: 'eventSourceRule'

请注意，我已经尝试过了eventHandler，EventHandler但这些都不起作用。这就是我收到的错误：

The CloudFormation template is invalid: Template error: instance of Fn::GetAtt references undefined resource EventHandlerLambdaFunction

我创建了一个无服务器 Redshift 实例，并尝试从 S3 存储桶导入 CSV 文件。

我创建了一个具有完整 Redshift + Redshift 无服务器访问权限和 S3 读取访问权限的 IAM 角色，并将该角色添加为Serverless Configuration的Permissions设置下的默认角色。基本上，我已经尝试根据文档做任何我认为必要的事情。
