TypeError: logging.log不是一个函数JavaScript Google功能

Question

关于这个问题，我已经找过了，什么也找不到。

我已经部署了一些用JavaScript编写的Google函数，它利用以下函数来报告错误。这些函数成功运行，但我收到了以下错误：

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

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

reportError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]

目前，通过将“logging”变量的初始化更改为，将YOUR_PROJECT_ID替换为创建这些云函数的项目id：

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

应该管用的。

您可以通过多种方式更改代码，但根据您在这里发布的新版本(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]

此更改基于下面的例子。
