我尝试使用AWS IOT服务器配置WSO2 DAS mqtt接收器，如下所述。
<?xml version="1.0" encoding="UTF-8"?>
<eventReceiver name="mqttIot" statistics="disable" trace="disable" xmlns="http://wso2.org/carbon/eventreceiver">
<from eventAdapterType="mqtt">
<property name="topic">/device-data</property>
<property name="cleanSession">true</property>
<property name="url">tcp://<url>:8883</property>
</from>
<mapping customMapping="disable" type="text"/>
<to streamName="sonsor.in.event.data.stream" version="1.0.0"/>
</eventReceiver>
还尝试更改端口8883和443.但得到相同的错误。

这适用于WSO2 ESB上的入站端点。我需要在DAS方面进行任何其他配置吗？
