Error 4422

Hello,

Any query leads to error code 4422. I have been writing some PHP code to get access to some data stored in our Zoho CRM following the Developer API Help pages but I keep getting the error code 4422: There is no data to show, no matter which query I send.

My code worked above few days ago, and now dont. I change nothing in it.

Can it be connected with new Zoho UI update? There is my code :

$url="https://crm.zoho.com/crm/private/xml/Leads/searchRecords?";
$query="authtoken=".$auth."&scope=crmapi&fromIndex=1&toIndex=".$number_of_elements."&criteria=(".$search_marker.":".$search_marker_value.")";
