Firebase注册令牌无效 . 检查令牌格式

这个问题之前已被多次询问和回答，但我无法弄清楚我做错了什么 . 从Firebase控制台向整个应用程序发送通知有效，但是如果我发送到单个令牌，我在firebase控制台中收到错误：“Firebase无效注册令牌 . 检查令牌格式”

我在Iphone设备上测试应用程序 .

• 在https://developer.apple.com/account/ios/authkey/创建了新密钥，下载了p8文件

• 从https://developer.apple.com/account/#/membership/获得了团队ID

• 在设置/ Cloud 消息传递下的firebase控制台中上传了.p8文件
  在目标/功能/推送通知下的.xcworspace中的

• ：ON

• myproject.entitlements文件包含APS环境字符串开发 .

注意：在developer.apple.com中，在APP ID下，如果单击myApp id并向下滚动，推送通知可配置和开发将显示为黄色而不是绿色 .
