Hello
When a driver opens or views a Sales Order, Odoo automatically looks in the background to see if there are any related tasks or projects linked to that order.
To find these projects, Odoo's system performs an internal search across the database using a field called reinvoiced_sale_order_id.
**Responsible method for this warning: def_compute_project_ids(self)
Options to resolve this:
→ Updating the driver group's access permissions to give them "Read-Only" clearance for the background project model OR
→ Applying a minor backend code adjustment in the relative method.
Hope this helps you
Thanks

Hello, 

This behavior is likely related to changes introduced in Odoo 19 or a recent update where Sales Orders now trigger access to linked Project fields in the background.

Since the error specifically mentions reinvoiced_sale_order_id on project.project, granting access to the field alone is usually not sufficient. The affected users must also have the necessary read access to the related Project records and any record rules that apply to them.

I would recommend reviewing:

• Access rights on the project.project model
• Record rules for the custom driver group
• Any inherited views or customizations that expose project-related information from Sales Orders

Since the same configuration worked in Odoo 18, comparing the security settings and view changes after the upgrade may help identify the dependency that was introduced.

Hope this works for you! If you need any help implementing this or want a more optimized approach, feel free to reach out for further discussion.
