salesforce connector in Mule - SOQL long query is not working properly for some objects - like product2

Question

I am facing an issue while running product2 SOQL long query in Mule salesforce Connector. I am able to run and got successful json message with certain fields like Id, Name, ProductCode, Description etc . But some other fields are not working like... Units__c, Stock_Item__c, Sub_Category__c etc. Non working fields are not available as well while I was selecting with "Query builder" in "DataSense Query Language". I guess those fields are customs made from my organization. But All kinds of queries are working perfectly on Salesforce developer console. I am looking for solution so that i can invoke all the fields with result from salesforce product object.

• My GET URL : http://localhost:8081/xxxxxxx/product2?lastModifiedDate=20180629215028
• AnyPoint Studio Version: 6.4.2
• MuleRuntime 3.9.0
• Salesforce Connector - Mule 3 - version : 8.6.0
• salesforce API version 40
• salesfroce url :https://xxxxxxxxx.cs96.my.salesforce.com/services/Soap/u/40.0

Tried Also :

1. with Native Query Language. but unsuccessful.

Thanks in advance !
