False positive type error when chaining Query Builder methods on Eloquent Relations

[imKenjo18]

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

public function rootItems(): HasMany
{
    return $this->items()->whereNull('inventory_group_id');
}

Expected Behavior

The extension should recognize that chaining builder methods (like where(), whereNull(), orderBy()) on a Relation object returns the Relation object, not the Builder.

Environment

• Laravel 12
• Other extensions: laravel.vscode-laravel

[imKenjo18]

$this->hasMany(InventoryItem::class)->whereNull('inventory_group_id') doesn't show an error.

Thank you for the test case. This seems to be caused by multiple ide-helpers used, namely _ide_helper (additional generated stubs which sometimes contain wrong declarations).

We'll try to repro the issue first.
