When a catalog item that has variable(s) with default value is submitted via REST API, the expected behavior is that default value should appear on the generated RITM but the variable is empty.

If the same item is submitted from portal/platform it is working as expected.ReleaseQuebecCausePRB1514483-> https://support.servicenow.com/problem.do?sys_id=d6133f7cdbfdf814fa192183ca961930&sysparm_view=cspResolutionThere is no workaround available for this PRB as the fix is made to the Java layer.
