Node.js 谷歌云运行返回错误503-服务不可用

由于某种原因，我无法发现，CloudRun总是返回503-Unavailable。不管我做什么。这在本地起作用，所以我不知道可能是什么问题。应用程序的所有其他端点都正常工作。一切都正常运行，但由于某种原因，此请求仅在本地主机上有效，但部署到GCR时，它不起作用

我想做的是上传一个文件到谷歌硬盘。以下是请求的逻辑：

router.post("/upload", async(req, res)=>{
  const payload = req.body;
  const resource = {
    name: payload.fileName || "Picture",
    driveId: process.env.DRIVE_ID
  };
  const uploadedFile = await uploadToTeamDrive(payload.imgData, resource).catch(error=>{
    console.error(`Error uploading file to team drive: ${error.toString()}`);
    gapiError(res, error);
  });
  if(!uploadedFile){ return; }
  res.status(201).send({success: true});
});

const uploadToTeamDrive = async(base64Img, resource)=>{
  const base64String = base64Img.split(",")[1];
  const imgData = Readable.from(Buffer.from(base64String, "base64"));
  const mimeType = base64Img.split(",")[0].split(";")[0].split(":")[1];
  const scopes = ["https://www.googleapis.com/auth/drive"];
  const client = await getClient(scopes);
  const service = google.drive({version: "v3", auth: client});
  const request = await service.files.create({
    media: {
      body: imgData,
      mimeType: mimeType
    },
    requestBody: resource,
    fields: "id,webViewLink,name,thumbnailLink,iconLink",
    supportsAllDrives: true
  });
  const file = request.data;
  return file;
}

这是来自云运行的日志所说的：

我已经采纳了报告中的所有建议，但似乎没有任何东西给我暗示。日志上没有更多内容，我已经查看了，似乎没有发现任何问题。

多亏了的建议，我才能够在本地对容器进行故障排除。我意识到出于某种原因，导致问题的原因是：

const imgData = Readable.from(Buffer.from(base64String, "base64"));

这行代码在windows上工作，windows是我的开发环境，但在linux（容器环境）上不工作。感谢您，我将该行代码更改为：

const theBuff = Buffer.from(base64String, "base64");
const imgData = new PassThrough();
imgData.end(theBuff);

上面的内容在linux上似乎很好，现在错误消失了。总之，这不是谷歌云运行问题，而是环境代码问题。我仍然要调查错误的原因。如果有人知道，请提供一些启示。

您是在本地尝试了容器还是只尝试了代码？@guillaumeblaquier只尝试了代码。我想我需要在本地测试这个容器。是的，两个都试一下。检查nodeJS运行时版本是否相同，以及安装的依赖项是否相同。
