Hi - does anyone know if there's a way to update custom fields in Zoho Connect tasks?

I have tried passing parameters but it returns "errorCode":"EXTRA_PARAM_FOUND","devReason":"Extra param found 'customRecords'"

1. map1 = Map();
2. map2 = Map();
3. map3 = Map();
4. map1.put("id","185487000004515175");
5. map1.put("value"," TEST");
6. map2.put("185487000004518044", map1);
7. map3.put("customRecords", map2);
8. 
   
9. sectionTasks = response.get("sectionTasks").get("tasks");
10. for each  rec in sectionTasks
11. {
12. title = rec.getJSON("shortTitle").getJSON("text");
13. id = rec.get("id");
14. if(title == "Test")
15. {
16. response = invokeurl
17. ​[                                           
18. url :https://connect.zoho.com/pulse/api/updateTask?scopeID= + scopeID + "&taskId=" + id
19. type :POST
20. parameters: map3
21. connection:
22. ];}}
