We are trying to use the kint() or drump() debugging functions inside twig templates in Drupal 8 but both does not seem to be working even though we have tried all the approces to get them working available online.
I have renamed my default.services.yml file to services.yml and set twig.config debug, auto reload and cache to true, yet I can't get any output out from those functions; however, it does not fail with a non-existent function error either.
When I try to use the dsm() function in my controllers or other files outside twig templates, it works as expected.
Any idea where the problem might be?
Thanks a lot in advance.
