I have rest_export view to generate json output of nodes. I'm trying to output a the upload date of files in a multivalue filefield, but can't find a solution. I tried to use the "rewrite results" option of the filefield in the view using twig as follows:
{% for item in field_myfiles %} {{ item.entity.timestamp|date("Y-m-d H:i:s") }} {% endfor %}
But it just does not work. Any hints how to achieve this?
