SendEachForMulticastAsync

Can any one please let me know the reason why this comes "At least one message is required" ?
while calling await FirebaseMessaging.DefaultInstance.SendEachForMulticastAsync(message);

There is valid payload, but still at times , does not know why this is occurring

If any one can share more details, please do share...

Error sending SendEachForMulticastAsync message: At least one message is required

首先使用报告中的 payload 重现 FirebaseMessaging.DefaultInstance.SendEachForMulticastAsync(message) 调用，并在调用前立即检查 message 对象。该 issue 未指定文件或测试；要完成此任务，需要确认重现并记录原因，或为间歇性错误“At least one message is required”提供范围明确的修复。
