Mule 将Soap异常跳过到Fork和Join模式中

目前，我有一个带有实现Fork和Join模式的流，其中并行调用同一服务5次。当服务未获得此信息时，返回一个soap错误。当我测试Fork和Join服务时，如果其中一个调用不令人满意，就会失败。如何忽略获取数据的服务的异常跳过以防止主服务失败

这是我的流程

<mulexml:namespace-manager includeConfigNamespaces="true">
<mulexml:namespace prefix="sol" uri=".." />
</mulexml:namespace-manager>

    <set-session-variable variableName="var" value="#[message.payload.substring(message.payload.indexOf('string')+4,message.payload.indexOf('string')+16)]" doc:name="var"/>
    <set-variable variableName="var2" value="#[message.payload.substring(message.payload.indexOf('string')+4,message.payload.indexOf('string')+16)]" doc:name="svar"/>

            </message-properties-transformer>
        </vm:outbound-endpoint>

        </vm:inbound-endpoint>
    </request-reply>
