Repeater MorphToMany

Hi everyone! I'm having a rough time with managing a MorphToMany relationship with a repeater. I'm currently managing permissions, roles and users. Model/Permission.php

public function roles(): MorphToMany
{
    return $this->morphedByMany(Role::class, 'grantable');
}

public function users(): MorphToMany
{
    return $this->morphedByMany(User::class, 'grantable');
}

public function roles(): MorphToMany
{
    return $this->morphedByMany(Role::class, 'grantable');
}

public function users(): MorphToMany
{
    return $this->morphedByMany(User::class, 'grantable');
}

Model/User.php:

public function permissions(): MorphToMany
{
    return $this->morphToMany(Permission::class, 'grantable');
}

public function permissions(): MorphToMany
{
    return $this->morphToMany(Permission::class, 'grantable');
}

Model/Role.php:

public function permissions(): MorphToMany
{
    return $this->morphToMany(Permission::class, 'grantable');
}

public function permissions(): MorphToMany
{
    return $this->morphToMany(Permission::class, 'grantable');
}

Logic works fine, except the Repeater. I followed this documentation: https://filamentphp.com/docs/3.x/forms/fields/repeater#integrating-with-a-belongstomany-eloquent-relationship and created the pivot class:

class Grantable extends Pivot
{
    use HasFactory;

    protected $table = 'grantables';

    public function permission(): BelongsTo
    {
        return $this->belongsTo(Permission::class);
    }

    public function role(): BelongsTo
    {
       return $this->belongsTo(Role::class); 
    }
}

class Grantable extends Pivot
{
    use HasFactory;

    protected $table = 'grantables';

    public function permission(): BelongsTo
    {
        return $this->belongsTo(Permission::class);
    }

    public function role(): BelongsTo
    {
       return $this->belongsTo(Role::class); 
    }
}

and in Model/Permission.php:

public function grantables(): HasMany
{
    return $this->hasMany(Grantable::class);
}

public function grantables(): HasMany
{
    return $this->hasMany(Grantable::class);
}

Then in my PermissionResource I have:

Section::make()
    ->schema([
        Repeater::make('grantables')
            ->relationship()
            ->simple(
                Select::make('grantable_id')
                    ->relationship(
                        'role',
                        'name',
                        fn(Builder $query) => $query->orderBy('order'),
                    ),
            )
            ->deleteAction(
                fn (Action $action) => $action->requiresConfirmation(),
            )
            ->addActionLabel('Assegna a un altro ruolo')
            ->reorderable(false)
            ->label('Scegli un ruolo')
            ->grid(2)
    ])
    ->heading('A quali ruoli lo vuoi assegnare?')
    ->hiddenOn('edit'),

Section::make()
    ->schema([
        Repeater::make('grantables')
            ->relationship()
            ->simple(
                Select::make('grantable_id')
                    ->relationship(
                        'role',
                        'name',
                        fn(Builder $query) => $query->orderBy('order'),
                    ),
            )
            ->deleteAction(
                fn (Action $action) => $action->requiresConfirmation(),
            )
            ->addActionLabel('Assegna a un altro ruolo')
            ->reorderable(false)
            ->label('Scegli un ruolo')
            ->grid(2)
    ])
    ->heading('A quali ruoli lo vuoi assegnare?')
    ->hiddenOn('edit'),

But when I try to save I get this error: SQLSTATE[HY000]: General error: 1364 Field 'grantable_type' doesn't have a default value which I think it means that it cannot manage the grantable_type column with the path to the model. Any idea how to solve? Thanks everyone
