wso2 esb twitter连接器未调用twitter api

我正在代理服务中使用WSO2 ESB Twitter连接器操作。代理配置如下所示

<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse" name="twitter_test_proxy" transports="http https" startOnLoad="true" trace="disable">
    <target>
        <inSequence>
            <twitter.init configKey="twitter_init"/>
            <twitter.getTopTrendPlaces configKey="twitter_init">
                <id>23424975</id>
            </twitter.getTopTrendPlaces>
        </inSequence>
        <outSequence/>
        <faultSequence/>
    </target>
</proxy>

23424975

我将twitter连接器导入esb并启用它。然后，所有工件（代理服务和twitter_init local entry）都部署在ESB中。调用代理服务后，我注意到twitter连接器没有调用预期的后端twitter API。我已经启用了wire调试和调试日志，如下所示。原因是什么？我正在使用WSO2 ESB 4.8.1。我按照创建配置时给出的说明进行操作

我只需对代理稍加修改就可以解决上述问题。我添加了respond mediator并获得了预期结果。工作代理如下所示
