Hi everyone,

I'm asking for your help with a problem I can't solve in odoo 17. My reports (quotations, sales invoices) are randomly generated empty.Sometimes the report is displayed perfectly. On another attempt, it was almost empty. I have no particular errors in the logs. So I don't understand what could be causing this type of bug. Has anyone had this problem before?
