Not able to Create AR invoice in Fusion through rest api

I am creating an AR invoice in Fusion through the REST API. There is a descriptive flexfield (DFF) on the header level called "context value." When we pass "Segment Code" as the value for this field, it opens three list of values (LOV) based DFF fields. We need to send values for these three fields during the creation of the AR invoice. However, when I try to send this payload, I am encountering an error.Could you please share a sample payload to send the values in these three fields?.

please check the attached screeen shot of fusion ERP for your reference.
