Hey!
I need to read a json file in UE 5.2.1, so I enabled the JSON Utilitities plugin that was added back in 5.0. After enabling it and restarting, some new nodes appeared in the editor, but not all of the nodes I’m supposed to have.

I specifically want to use this, but it doesn’t seem to exist.

Thanks!
