I am interacting with a third party service and I get the following responses :

if token valid 200 response

{
 ...
 "valid_until": "2018-09-21T00:00:00Z"
 }

if token is invalid I get 200 response with :

	{       "status": false, 

		"error": "Invalid Token Format!"

	}

I have the following extract policy

<ExtractVariables   name="Extract-valid-until-date">
    <DisplayName>Extract token chorus</DisplayName>
    <Source>chorusresponse</Source>
    <JSONPayload>
        <Variable name="valid_until">
            <JSONPath>$.valid_until</JSONPath>
        </Variable>
        <Variable name="response_error">
            <JSONPath>$.error</JSONPath>
        </Variable>
    </JSONPayload>
</ExtractVariables>

this is falling with following error if no valid_until date present in the json response:

{"fault":"{\"detail\":{\"errorcode\":\"steps.extractvariables.InvalidJSONPath\"},\"faultstring\":\"Invalid JSON path $.valid_until in policy Extract-valid-until-date.\"}"}

I tried $.?valid_until $.?(valid_until) but still not working,

is there any why to avoid error if the value is not present

Many thanks

Hi, you can use javascript policy.And in that you can use sth like

 var reqPayload = JSON.parse(context.getVariable('request.content'));
 var flag=reqPayload.hasOwnProperty('name');
 print(flag);

and use the flag accordingly. hasOwnProperty() will check if the property 'name' exists or not in payload. If not then will return false otherwise true.
