Getting error while integrating Jira with .Net Framework

[ADITYA CHOWDHURY]

Hi Everyone,

I am trying to integrate the Jira with .Net Framework via atlassian SDK but when I am trying to create a ticket, I am getting an error in CustomField as below:

System.InvalidOperationException: 'Response Status Code: 400.
Response Content: {"errorMessages":[],"errors":

{"Macro":"expected Object",
"Work_Group":"expected Object",
"Work_Type":"expected Object"}}

Macro, Work_Group, and Work_Type are all cascading type. The flow for subgroup is : Macro- > Work_Group-> Work_Type

I am trying to do it like below:

issue.CustomFields.AddArray("Macro", "Windows Virtual Desktop (WVD) (AASET-2609460)");

Please guide me to resolve the issue

Thanks
