I am trying to create procedure migration in laravel but I am getting syntex error every time I tried so but didn't make it work

Below is the code

$this->addSql("CREATE PROCEDURE Type_Store_Sync(IN name_it VARCHAR(255), IN guid VARCHAR(32), IN type VARCHAR(10), IN orgid INT(11), IN scheme VARCHAR(6)) LANGUAGE SQL
        BEGIN
            CALL mysql.lambda_async( 
  'arn:aws:lambda:eu-west-2::function:triggersync',
                CONCAT('{ \"name\" : ', REPLACE(name_it,'\\','\\\\'), ', \"guid\" : ', guid,', \"type\" : ', type,', \"orgid\" : ', orgid,', \"scheme\" :', scheme,'\"}')                
            );
        END");
