Costs doesn't work any longer since update about costs HOT 4 CLOSED

I upgraded my debian server to Bookworm and thus PHP to version 8
Everything seems to work fine now

from costs.

So this was a PHP 7.4 issue.
Thanks for the feedback.

Hello, can you please provide us with the version of your GLPI and the related errors in the php-errors.log file?

The latest versions only fix the positioning of the dropdown and a warning that the identifier fields do not support negative numbers, with no changes to the functionality of the costs.

Hello,
We are using GLPI 10.0.7 ; I will upgrade it to 10.0.12 to check if the problem remains

Here is the log file content :
