Error: When trying to add a new store in the eBay-NetSuite Integration App, an error occurs at the NetSuite configuration process. The error Celigo bundle is not installed in NetSuite but the bundle is already installed and even updated. The issue occurred only for NetSuite Sandbox connection.

Solution: Re- authorize the existing NetSuite Connection and save the connection, then try to configure the NetSuite connection and the error is resolved.
