Google Cloud Functions中出现"Error: Cloud access token“

Question

我想要做的是执行用Node.js编写的云函数，并在GCE中创建vm实例。

我已经在GCE中实现了云函数来创建vm实例。我多次尝试执行云函数，但没有创建vm实例。

云函数运行时: Node.js 8

源代码如下所示。index.js

const Compute = require('@google-cloud/compute');
const compute = new Compute();
exports.startInstance = function startInstance(req, res) {
    const zone = compute.zone('us-central1-c');
    zone.createVM("test", {os: 'ubuntu'});
    console.log('instance start successfully');
res.status(200).send('Success start instance');
};

package.json

{
  "name": "startInstance",
  "version": "1.0.0",
  "description": "create gce instance",
  "main": "index.js",
  "dependencies": {
    "@google-cloud/compute": "1.0.0"
  }
}

错误有时会出现如下所示。

"textPayload": "Error: Could not refresh access token: Unsuccessful response status code. Request failed with status code 500\n    at Gaxios.request (/srv/node_modules/gaxios/build/src/gaxios.js:70:23)\n    at <anonymous>\n    at process._tickDomainCallback (internal/process/next_tick.js:229:7)",

  },

}

您能告诉我为什么在GCE中没有创建vm实例吗？

Answer 1

我将你的代码按原样重新生成，我得到了错误：

错误:字段‘zone’的值无效：‘us-cental1’。未知区

例如，我更新了您的代码以使用‘us-cental1-c’区域，它成功地创建了VM。
