parameter order incorrect in Set Privileges DataBase x User

[jitin-joseph]

error occured when the paramters were passed like mentioned in document
echo $api->setPrivilegesMySQL("DATABASENAME", "USERDB");

   {"warnings":null,"status":0,"errors":["The request failed. (Error ID: qb9qa7) Ask your hosting provider to research this error in cPanel & WHM’s main error log."],"data":null,"messages":null,"metadata":{}} 

but when i checked the library it was
public function setPrivilegesMySQL($user, $database) {

$func = "https://$this->cPanelUrl:$this->cPanelPort/execute/Mysql/set_privileges_on_database?user=$user&database=$database&privileges=ALL";
return $this->exe_cpanel($func);

}

so the correct format is
echo $api->setPrivilegesMySQL("USERDB","DATABASENAME");
