Date and datetime fields formatting and wrong data type issue when update or create

Hello,

I'm trying to update a field in the Potentials module;update a datetime field with a date field value. But, I'm getting the error below.

Code below:

// get Deal records
dealDetails = zoho.crm.getRecordById("Potentials",dealID);

// get site survey schedule date
site_survey_date = dealDetails.get("Site_Survey_Schedule_Date_2");

update_date = zoho.crm.update("Potentials",dealID,Map:String({"test_datetime":site_survey_date}));

Error below:

{"code":"INVALID_DATA","details":{"expected_data_type":"datetime","api_name":"test_datetime"},"message":"invalid data","status":"error"}
