I have coded a plugin to replace the email received at each order by the woocommerce administrator, I want to replace this email with an excel file generated with the order information using an excel file template that I put in the plugin folder
The problem is that when I place an order I have an error message in front-end as the order does not pass, but I still received a confirmation email but without the excel file.
I tried to debug but without really having any result, do you think my code is a problem?
I already installed the PHPspreadseeet library, manually but also with a plugin : CBX PhpSpreedSheet Library

I see you don't have any get_serial_number and here it is:
function get_serial_number( $item ) {
// You can generate the serial number here
return $serial_number;
}
