ReferenceErrors

`data.cleared_required_reference`

A reference that can never be none is cleared on delete.

Area 5, Entities, stores and migrations; not declinable; the next step is usually the agent's.

example

entity Project {    id: Uuid}entity Todo {    id: Uuid    project_id: Project.id {        on_delete: OnDelete.cleared    }}

jadpo checkcheck failed: 1 error, 1 file

error Todo.project_id can't be cleared

--> main.jadpo:8:20

  |8 |         on_delete: OnDelete.cleared  |                    ^^^^^^^^^^^^^^^^ the field can't be `none`

reason: OnDelete.cleared sets the reference to none when the Project is deleted, which only an optional reference (Project.id?) can hold.
next: Make it Project.id?, or use OnDelete.restricted or OnDelete.cascade (agent)
