Hi all,

In the Odoo 19.0-20250928 (Community Edition), in the Project Tasks, there are several views. All of them work (kanban, list, pivot, activities,..) except the Calendar view. When trying to switch the view, the error message appears "Oops, Something went wrong..." with a detailed error description as follows"

Odoo Server Error

The workaround is to select "All tasks" -> set Calendar -> choose only the desired project name on the right side, under the month view. But I'd rather see this error fixed. Please help or suggest.

Hi,


The error occurs because the Calendar view in Project Tasks is referencing a missing field — planned_date_begin. This field is normally used by Odoo to determine when a task starts on the calendar, but it either doesn’t exist in your database or was removed during customization or migration. As a result, when Odoo tries to load the calendar view, it fails with the “Invalid field project.task.planned_date_begin” error.

To fix this, you can simply activate Developer Mode, locate the project.task.calendar view under Project → Configuration → Views, and edit it. Replace the missing planned_date_begin field with another date field that exists, such as date_deadline, in the XML definition of the view. This will let the calendar display tasks based on their due dates instead.

If you prefer to keep the original structure, you can also restore the missing fields by creating a small custom module that adds planned_date_begin and planned_date_end as datetime fields on the project.task model. Alternatively, upgrading or reinstalling the Project module may restore them automatically.

In short, the issue is caused by the calendar view calling a field that no longer exists. You can solve it either by updating the calendar view to use existing fields like date_deadline or by reintroducing the missing fields through a simple custom module.


Hope it helps
