Zoho Deluge Help - Search Records on custom field value

Zoho Deluge Help - Search Records on custom field value

I have created a function that searches for tasks on Zoho Desk based on a custom field. When executing the code, it fails with the following:

{"errorCode":"UNPROCESSABLE_ENTITY","message":"Extra query parameter 'cf_ticket_scheduled_date' is present in the input."}

I have searched the forums for this, and the code itself seems to be correct, but is throwing an error for the custom field. The code is below:

todayDate = today;
info todayDate;

queryValue = Map();
queryValue.put("cf_ticket_scheduled_date", todayDate);
info queryValue;

getAllTasks = zoho.desk.searchRecords(orgId.toLong(),"tasks",queryValue,1,100,"zohodesk");
info getAllTasks;

if(!getAllTasks.isEmpty())
{
    //do some more logic later
}


Any assistance on where I'm going wrong on this would be muchly appreciated.
