SQL "Duplicate entry" error when inserting into glpi_documents_items with Formcreator

[Windayz]

Hello,

I’m encountering an error when using the Formcreator plugin on GLPI (last release):

MySQL query error: Duplicate entry '6483-PluginFormcreatorFormAnswer-15445-0' for key 'glpi_documents_items.unicity'

This error occurs when the plugin tries to insert a relation between a document and a form answer, but the database rejects it because this entry already exists.

Context: GLPI version: 10.0.18 Formcreator version: 2.13.10

This error appears when creating or updating a form answer containing an attached document.

Expected behavior: The plugin should properly handle duplicates, either by checking for existence before inserting or updating the existing entry.

Steps to reproduce: Create a form with a file upload field. Submit an answer with an attached document. Submit the form again or update the answer. The error occurs during the insert.

Logs and errors:

Notes: I did not observe any PHP errors related to upload size or other server issues, indicating the problem comes from duplicate handling in the database.

Thanks in advance for your help.
