Google Chat Apps Script机器人已连接但无法接收事件求助

已完成的配置步骤 #

• 创建包含onMessage、onAddToSpace、onRemoveFromSpace处理器的Apps Script项目
• 将项目部署为Google Chat应用并复制Deployment ID
• 在Google Cloud Console的Google Chat API配置页面，设置连接类型为Apps Script，关联正确的Deployment ID，并将应用状态设为Live

问题现象 #

• 添加机器人或在空间中提及它时无任何响应：Chat中无回复（甚至没有默认的“Thanks for adding me”提示）
• Apps Script的Executions标签页无新运行记录
• 手动运行onMessage时因event对象未定义失败（此为正常情况）

已确认信息 #

• Deployment ID、Chat API配置、项目编号均匹配，但Google Chat从未调用脚本
• HTTP连接方式可正常工作，但需使用Apps Script实现更多功能

已尝试的排查操作 #

• 创建新部署并重新关联到Chat API配置
• 将机器人添加到全新空间以触发onAddToSpace
• 确认使用的是Workspace账户而非个人Gmail
