It seems like new O2System\Html\Element\Attributes() of type O2System\Html\Element\Attributes is incompatible with the declared type O2System\Html\Element\Attribute of property $attributes.

$output was never initialized. Although not strictly required by PHP, it is generally a good practice to add $output = array(); before regardless.
