I do not know if I am something missing, but I have a View in Drupal 8 and wanted to make a Template override in my theme, where I would print-out the image URL of one field and set it as "background-image" via inline CSS.
So I turned on theme debugging to see the template suggestions and picked
views-view-field.html.twig, copied the file to my theme, renamed it to match the suggestion, cleared the cache and it looks like the template override is working.
But all the variables I am trying to print-out are blank, even after clearing the cache the field just disappeared. When I try to dump() or kint() any variable written in the file (view, field, row, output) it prints "null" or completelly nothing.
What am I doing wrong?
I am sure template override works, because when I type regular text in a file it gets printed out, but all the variables are somehow missing and I can not print anything out of them.
