Hello
I have one Odata service with request URI as below:-
/sap/opu/odata/sap/ZQ316_CHATBOT_SRV/PurchaseOrderItemSet?$filter=PoNumber eq '3000000004' &$format=json
Now when i call this URI from gateway client its giving me expected result. Now my purpose is to call this odata service from my XSJS through SCP cloud. I have called gateway service from xsjs successfully for other Odata service without filter expression. But when i am using filter to call this service from xsjs getting this error message :-

Here is the request message i have built in xsjs :-
request = new $.web.WebRequest($.net.http.GET,"/PurchaseOrderItemSet?$filter=PoNumber eq '"+vnum+"' &$format=json");
