RelationManager Call to undefined method HasMany::getQualifiedRelatedKeyName

Hey, i do experience issues while implementing a RelationManager for my Filament application that i can not wrap my head around. I do have a "Container" model that should be able to be related to other Containers - it does have a parent_id column as well as a parent (BelongsTo) & children (HasMany) relationship. However, when i try to "put one Container into the other" by attaching it, i do get the following exception: https://flareapp.io/share/LPdKbvdm#context
I really don't understand why it does try to call getQualifiedRelatedKeyName as this method has been removed from the Relation implementation in Laravel 5.5. This is how i have defined the relationship column in my migration:

Schema::create('containers', function (Blueprint $table) {
    $table->id();

    $table->foreignId('parent_id')
        ->nullable()
        ->constrained('containers');

    $table->timestamps();
});

Schema::create('containers', function (Blueprint $table) {
    $table->id();

    $table->foreignId('parent_id')
        ->nullable()
        ->constrained('containers');

    $table->timestamps();
});

This is how i have implemented the relationships on the Container Model:

class Container extends Model
{
    /**
     * The parent Container this Container is stored in.
     */
    public function parent(): BelongsTo
    {
        return $this->belongsTo(self::class, 'parent_id');
    }

    /**
     * The child Containers that are stored in this Container.
     */
    public function children(): HasMany
    {
        return $this->hasMany(self::class, 'parent_id');
    }
}

class Container extends Model
{
    /**
     * The parent Container this Container is stored in.
     */
    public function parent(): BelongsTo
    {
        return $this->belongsTo(self::class, 'parent_id');
    }

    /**
     * The child Containers that are stored in this Container.
     */
    public function children(): HasMany
    {
        return $this->hasMany(self::class, 'parent_id');
    }
}

This is how i have implemented the RelationManager:

class MyRelationManager extends RelationManager
{
    protected static string $relationship = 'children';

    public function table(Table $table): Table
    {
        return $table
            ->recordTitleAttribute('name')
            // ...
            ->inverseRelationship('parent');
    }
}

class MyRelationManager extends RelationManager
{
    protected static string $relationship = 'children';

    public function table(Table $table): Table
    {
        return $table
            ->recordTitleAttribute('name')
            // ...
            ->inverseRelationship('parent');
    }
}

Does anyone have an idea on what i am doing wrong? I do appreciate any help 🙂 Thank you
