[Haskell-cafe] stack ignores my config.yaml?

Hello haskellers, I'm trying to use stack scripting capabilities, but it gives me an error (and suggestion to fix it by adding some lines to extra-deps in config.yaml). However, adding this lines to config.yaml doesn't change anything. My script and config are here -  https://pastebin.com/PyRMQtqw   Any help would be appreciated.
