极光推送 通过registration_id 推送，报cannot find user by this audience

java后台通过registrationId点对点推送推送一直报错，后台代码如下：
PushPayload payload = PushPayload.newBuilder().
setPlatform(platform).
setAudience(Audience.registrationId(registrationId)).
setMessage(Message.content(message)).build();
PushResult result = jpushClient.sendPush(payload);
registrationId通过官网已发送消息给app端测试是能收到消息，证明registrationId是可用的，
但是一直报cannot find user by this audience，找不到推送目标，这怎么解。
