@google-cloud/pubsub NodeJS 库抛出“未捕获的类型错误：类扩展值未定义不是构造函数或 null”

Question

我正在实现一项服务来将消息发布到 Google Cloud Pub/Sub 主题。

import { PubSub } from '@google-cloud/pubsub'

import type { NotificationData } from './models/notification'

class NotificationService {
  private pubsubClient: PubSub
  private topicName = 'notifications'

  constructor() {
    this.pubsubClient = new PubSub()
  }

  async publishMessage(messageData: NotificationData) {
    const data = JSON.stringify(messageData)
    const dataBuffer = Buffer.from(data)

    try {
      const messageId = await this.pubsubClient
        .topic(this.topicName)
        .publishMessage({ data: dataBuffer })

      console.log(`Message published (id: ${messageId})`)
    } catch (error) {
      console.error('Error publishing message:', error)
    }
  }
}

export const notificationService = new NotificationService()

当我在前端（vue3）组件中导入并使用该服务时，应用程序无法加载，并出现以下错误：

Uncaught TypeError: Class extends value undefined is not a constructor or null

这发生在使用该服务的组件被渲染之前。我在图书馆问题或 stackoverflow 上的其他地方都找不到遇到相同问题的人。
