ApigeeLint:An appropriate check for a message body was not found on the enclosing Step or Flow:PO004

I am running my proxy through a CI/CD pipeline. It fails at Apigee Lint stage with this error>

What could be the issue

This is the Flow:

 <Flow name="QueryStatus">
            <Description/>
            <Request>
                <Step>

                    <FaultRules/>
                    <Name>EV-QueryStatus</Name>
                </Step>

            </Response>
            <Condition>(proxy.pathsuffix MatchesPath "/user/request/**") and (request.verb = "GET")</Condition>
        </Flow>

JS-QueryStatus.js

var pathSuffix = context.getVariable("proxy.pathsuffix");
var referenceNumber= context.getVariable('referenceNumber');
var queryStatusBasepath= context.getVariable('queryStatusBasepath');
print(referenceNumber);
if (pathSuffix ="/charge/request"+"/"+referenceNumber){
    var queryTargetPath = queryStatusBasepath+"/"+referenceNumber;
    context.setVariable ('queryTargetPath',queryTargetPath);}
