Zoho Voice and Zoho CRM integration

Zoho Voice and Zoho CRM integration

So, I created the connection between zohoCRM and ZohoVoice, I gave the Scope Value : ZohoVoice.sms.ALL permissions. 

And I went ahead and created a test function in CRM in order to test the sendBulk sms and keep getting error: "{"code":"ZVT010","message":"Extra parameter found.","status":"ERROR"}" 

Could you please help me figure this out? 
Here is the code: 

// test date 06/20/2023 12:30:00   
phones = {"+14444444444","+573333333333","+155555555555","+639999999999","+11111111111","+12222222222"};
smsParams = Map(); 
// These are just dummy numbers but I tested with real numbers
group = Collection();
for each phone in phones
{
smsParams.put("recipient",phone);
smsParams.put("message","test bulk SMS with same content😎");
smsParams.put("dataEncoding", 0);
group.insert(smsParams);
}
dataParams = Map();
dataParams.put("dataSet", group);
dataParams.put("scheduledTime", Scheduled_Date.toText().unixEpoch("EST").toString() );
info dataParams;
 response = invokeUrl [
type: POST
parameters: dataParams.toString()
connection: "zvoice"
];
info response;
return "Succesfully send bulk SMS";
