Http Task not retrying

Flowable Engine
1

I have my http task like this

 <serviceTask id="sid-B8FC8019-55DA-4771-818C-A4B11CC3B66F" name="DEBIT CHECK STATUS" flowable:type="http">
        <extensionElements>
            <flowable:field name="requestMethod">
                <flowable:string><![CDATA[POST]]></flowable:string>
            </flowable:field>
            <flowable:field name="requestUrl">
                <flowable:expression><![CDATA[${debitstatuscheckurl}]]></flowable:expression>
            </flowable:field>
            <flowable:field name="requestHeaders">
                <flowable:expression><![CDATA[${debitstatucheckrequestheaders}]]></flowable:expression>
            </flowable:field>
            <flowable:field name="requestBody">
                <flowable:expression><![CDATA[${debitresponse}]]></flowable:expression>
            </flowable:field>
            <flowable:field name="requestTimeout">
                <flowable:string><![CDATA[600000]]></flowable:string>
            </flowable:field>
            <flowable:field name="responseVariableName">
                <flowable:string><![CDATA[debitstatuscheckresponse]]></flowable:string>
            </flowable:field>
            <flowable:field name="failStatusCodes">
                <flowable:string><![CDATA[400]]></flowable:string>
            </flowable:field>
            <flowable:failedJobRetryTimeCycle>R5/PT5S</flowable:failedJobRetryTimeCycle>
            <flowable:field name="saveResponseParameters">
                <flowable:string><![CDATA[true]]></flowable:string>
            </flowable:field>
            <flowable:field name="resultVariablePrefix">
                <flowable:string><![CDATA[debitstatuscheckresponseprefix]]></flowable:string>
            </flowable:field>
            <flowable:field name="saveResponseParametersTransient">
                <flowable:string><![CDATA[true]]></flowable:string>
            </flowable:field>
            <flowable:field name="saveResponseVariableAsJson">
                <flowa`b`le:string><![CDATA[true]]></flowable:string>
            </flowable:field>
        </extensionElements>
    </serviceTask>

Now when the api sends 400 , it does not retry this specific http task 5 times, as configured.

Rather it goes to the service task node which startted execution of this async executor and starts executing that , (I guess that’s happening because execution cycle is failing).

But still it should execute this http task 5 times with an interval of 5s , but not happening.
Is there anything I am missing here?
