Logging 当我们在Groovy脚本mule 3.7.3中引发异常时，如何限制错误日志不打印在日志中

当我们在Groovy脚本mule中引发异常时，如何限制错误日志不打印在日志中。 下面是流程和响应

    <http:listener-config name="HTTP_Listener_Configuration" host="0.0.0.0" port="7475" doc:name="HTTP Listener Configuration"/>
        <flow name="ExceptionTestFlow">
            <http:listener config-ref="HTTP_Listener_Configuration" path="/test" doc:name="HTTP"/>
            <logger level="INFO" doc:name="Logger"/>
            <scripting:component doc:name="Groovy">
                <scripting:script engine="Groovy"><![CDATA[throw new Exception("Invalid Message")]]></scripting:script>
            </scripting:component>
            <catch-exception-strategy doc:name="Catch Exception Strategy">
                <logger message="#[payload]" level="INFO" doc:name="Logger"/>
            </catch-exception-strategy>
        </flow>
