求帮助 在服务器通过厂商发送单播消息时 遇到个这样的问题

友盟返回参数 400 : "{"ret":"FAIL","data":{"error_msg":"该应用未开通选择安卓通道策略","error_code":"3009"}}"

这是我的请求参数 Post Body: {"appkey":"67f71e16be8a374b4e8555bb","type":"unicast","device_tokens":"AnPL_XlC5ZDWduar73Ok3VU3VGxwv0j7GJkrGM5fMBB","payload":{"body":{"title":"测试","text":"消息体"},"display_type":"notification"},"policy":{"channel_strategy":{"default":3}},"timestamp":"1744787116225"}

有没有大神了解问题出在哪了
