我正在尝试使用 probot 应用程序从 Github 接收 webhook，但每次尝试此操作时，都会出现{"message":"Service Unavailable"}错误。

Github 将此有效负载发送到 AWS Lambda 函数，通过谷歌搜索（我认为）这是一个没有足够节点来处理请求数量的问题。

要么我的代码有问题，要么配置有错误。

我正在使用无服务器框架上传到 AWS lambda。

这是代码失败的部分（日志中没有错误消息，机器人刚刚退出）：

const yamlFile = async (context) => {
  try {
    console.log("trying to get yaml")
    var yamlfile = await context.octokit.repos.getContent({
      owner: context.payload.repository.owner.login,
      repo: context.payload.repository.name,
      path: ".bit/config.yml",
    });
    console.log(yamlfile)
  } catch (e) {
    console.log("Error with getting content of yaml");
    console.log(e)
    return null
  }
  console.log("got yaml, but no content yet");
  yamlfile = Buffer.from(yamlfile.data.content, 'base64').toString()
  console.log(yamlfile)
  try {
    let fileContents = yamlfile
    configyml = yaml.load(fileContents);
  } catch (e) {
    const issueBody = context.issue({
      title: "[ERROR] Please read",
      body: `There was an issue parsing the config file of this course. Please contact your counselor and send them the below error.\n${e}`,
    });

    context.octokit.issues.create(issueBody)
    console.log("ERROR: " + e);
    return null
  }
  console.log("returining configyml")
  return configyml;
}

该函数yamlFile()在我们的主函数中被调用：

let currentStep = ""
let configData = await data.yamlFile(context);
console.log(configData)
if (configData == null) {
  console.log("null config data");
  return
}
