Cannot clone a product

Hello

I get the following error printing above the header when trying to clone a product:

======================================
Requested URL: /dolibarr/htdocs/product/card.php?id=168&action=confirm_clone&confirm=yes&clone_ref=able-e&clone_content=on&clone_prices=&clone_composition=on

======================================

The product does have a barcode value that is not null

Thank you for your input!

Which version of Dolibarr ?

Installed last week 6.0.3

I reinstalled from scratch it is now working fine.
The probable cause is the installation of a module that was deprecated and caused major issues
We removed it from the /custom directory but it looks like it left some nasty scars in the DB and files as well (broken links)
I did not realize the “extra fields” module might not work after Dolibarr version 3.9
Is there anything to create extra fields, as we really need them?

Thanks!
