Filament Manage Related with hasMany and hasMany with Repeater

I have 3 tables : "Process", "Units" and "UnitsItems" 

process
    id - integer
    name - string
    number_process - float
    hasMany
      units - process_id
units
    id - integer
    name - string
    process_id - integer
    address - string
    hasMany
    items_units - units_id

items_units
    id - integer
    name - string
    value - float
    units_id - integer

The problem is that when I create a new unit, I must add 1 (or more) itemsunits that are connected to a unit, through the "repeater". A unit can be linked to 1 or many unit items. But when I try to add some unit items it has the following error.

Call to a member function itemsUnits() on null
