After extending Emotion Component Template, function call results in an Internal Server Error 500


I am extending component_manufacturer_slider in order to replace the href attribute of each manufacturer element.

When I call public functions of attribute struct on supplier it results in a server erro 500.

Both {$supplier.attributes.core->toArray()|var_dump} and {$supplier.attributes.core->get(“my_attribute_name”)|var_dump} result in error and do not return what I want.

Any suggestions on how to access protected storage object array values? as the typical get does not work for an unknown reason to me.
