Big thx Alex!
Just checked your vid - i have exact the same setup. However, my json tag never triggers. Maybe there can be any error which i can check in the logs somewhere or?
The only reason why the tag may not trigger is a problem with the trigger, you need to check that. Maybe you have a typo in the client name or something like that.
Try uninstalling Data Client (including in temelpaths) and reinstalling it from GitHub: GitHub - stape-io/data-client: Data Client for Google Tag Manager Server Side
Also, for tests, try removing the Adsamurai client, maybe there are some conflicts there.
This is a local configuration issue on your container. You should try different options for experiments - old screenshots show that for some reason Data Client doesn’t process requests at all, that’s why your tag doesn’t work.
