TypeError: logging.log 不是函数 JavaScript Google Cloud 函数

Question

我已经搜索过，但没有找到关于这个问题的任何内容。

我已经部署了一些用 JavaScript 编写的 Google Cloud 函数，它们利用以下函数来报告错误。函数运行成功，但我收到以下错误：

TypeError: logging.log 不是函数 在 reportError (/user_code/index.js:158:23)

const logging = require('@google-cloud/logging');

报告错误函数：

function reportError(err, context = {}) {

  const logName = 'errors';
  const log = logging.log(logName);

  // https://cloud.google.com/logging/docs/api/ref_v2beta1/rest/v2beta1/MonitoredResource
  const metadata = {
    resource: {
      type: 'cloud_function',
      labels: {function_name: process.env.FUNCTION_NAME},
    },
  };

  // https://cloud.google.com/error-reporting/reference/rest/v1beta1/ErrorEvent
  const errorEvent = {
    message: err.stack,
    serviceContext: {
      service: process.env.FUNCTION_NAME,
      resourceType: 'cloud_function',
    },
    context: context,
  };

  // Write the error log entry
  return new Promise((resolve, reject) => {
    log.write(log.entry(metadata, errorEvent), (error) => {
      if (error) {
       return reject(error);
      }
      return resolve();
    });
  });
}
// [END reporterror]

就目前而言，通过将“日志记录”变量的初始化更改为，将 YOUR_PROJECT_ID 替换为创建这些 Cloud Function 的项目 ID：

const logging = new (require('@googlecloud/logging')).Logging({projectId:'YOUR_PROJECT_ID'});

它应该可以工作。

您可以通过多种方式更改代码，但根据您在此处发布的内容将是新版本（只需相应地编辑 projectId 变量）：

const google_cloud_logging = require('@google-cloud/logging');

function reportError(err, context = {}) {

  const logName = 'errors';

  const projectId = '';

  const logging = new google_cloud_logging.Logging({projectId: projectId});

  const log = logging.log(logName);

  // https://cloud.google.com/logging/docs/api/ref_v2beta1/rest/v2beta1/MonitoredResource
  const metadata = {
    resource: {
      type: 'cloud_function',
      labels: {function_name: process.env.FUNCTION_NAME},
    },
  };

  // https://cloud.google.com/error-reporting/reference/rest/v1beta1/ErrorEvent
  const errorEvent = {
    message: err.stack,
    serviceContext: {
      service: process.env.FUNCTION_NAME,
      resourceType: 'cloud_function',
    },
    context: context,
  };

  // Write the error log entry
  return new Promise((resolve, reject) => {
    log.write(log.entry(metadata, errorEvent), (error) => {
      if (error) {
       return reject(error);
      }
      return resolve();
    });
  });
}
// [END reporterror]

此更改基于following example。
