The solution provided by @juergen in comments is working fine, that is, Add a ;
after the insert statement (before the END) Thanks for finding my mistake. I was looking for it for about 4 hours so Answer is here:
DELIMITER //
CREATE TRIGGER product_table_after_insert
AFTER INSERT
ON product_table
FOR EACH ROW
BEGIN
DECLARE l_product_description varchar(500);
DECLARE l_product_number int;
set @l_table_name = 'product_table';
set @l_action = 'INSERT';
set @l_table_column = 'all columns';
set @l_description = 'new row inserted';
select p.product_description ,p.product_number
into @l_product_description, @l_product_number
from product_table p
where p.product_description =
(select max(pg.product_number)
from product_table pg);
-- Insert record into audit table
INSERT INTO audit_table_test
( table_name,
changed_row_id,
action,
table_column,
change_desciption,
change_time
)
VALUES
( l_table_name,
l_product_number,
l_action,
l_table_column,
l_description,
SYSDATE()
); //<<---- Semicolon needed to be here
END

So your code should be as per below,
DELIMITER //
CREATE TRIGGER product_table_after_insert
AFTER INSERT
ON product_table FOR EACH ROW
BEGIN
DECLARE l_product_description varchar(500);
DECLARE l_product_number int;
set @l_table_name = 'product_table';
set @l_action = 'INSERT';
set @l_table_column = 'all columns';
set @l_description = 'new row inserted';
select p.product_description ,p.product_number into @l_product_description, @l_product_number from product_table p where p.product_description = (select max(pg.product_number)from product_table pg);
-- Insert record into audit table
INSERT INTO audit_table_test
( table_name,
changed_row_id,
action,
table_column,
change_desciption,
change_time
)
VALUES
( l_table_name,
l_product_number,
l_action,
l_table_column,
l_description,
SYSDATE()
);
END
//
DELIMITER
