我正在尝试让推送通知在iOS上运行。当使用"；发送"；，但在使用"；sendToDevice"；。这真的很奇怪。我遵守了这里的所有说明(https://firebase.google.com/docs/cloud-messaging/ios/client)，但它仍然不起作用。我已经在我的开发者帐户和Firebase控制台中设置了APN文件，我可以直接从Firebase面板发送推送。我已经附上了我的firebase函数代码以及我的AppDelegate。我做错了什么？谢谢你的帮助。

事实证明，iOS要求您传递标题和正文，否则它不会显示通知。像这样的东西行得通。
const payload = {
"notification":{
"title": "Needed title",
"body": "Needed body"
},
"data" : {
"lostPetId" : context.params.lostPetId,
"lostPetName": lostPet.name,
"messageType": "1"
}
}
