The property path does not exist. Although not strictly required by PHP, it is generally a best practice to declare properties explicitly.

        $this->elementId .= uniqid();

It seems like function(...) { /* ... */ } of type callable is incompatible with the declared type null of property $branchCallback.

The expression return $this returns the type Yeelight\Services\Tree\Tree which is incompatible with the documented return type Illuminate\Database\Eloquent\Model.
