API to Retrieve a MultiSelect Fields

API to Retrieve a MultiSelect Fields

Hi Team, 
I'm trying to a retrive a Mutliselect Field from a request but I keep getting error below. 

{"response_status":{"status_code":4000,"messages":[{"status_code":4001,"type":"failed","message":"Invalid Input","fields":["udf_fields.udf_multiselect_16202"]}],"status":"failed"}}


these are fields I have tried to  filter 

"fields_required" : ["subject","priority","udf_fields.udf_multiselect_16202","udf_fields.udf_date_15308"]

I'm also pasting below the
