Does Groupcheck still work?

Hey, I'm very new to roll20 and have 0 coding experience, so most of what i've been reading is going way over my head, I've got a question about groupcheck api... I can't seem to get it to work with jumpstart, legacy, or any dnd sheets. I always get api errors that require me to restart it. Does it just not work? or am I missing something? Any help is appreciated, Thank you.

Here are a few screenshots of what i assume are important? The command I try to use is copied from the help page for groupcheck. !group-check --whisper --Dexterity Save

Have you configured the script for the 5E Shaped sheet?  Restart your script sandbox and type !group-check-config into the chat window, or jump straight to !group-check-config --import 5E-Shaped .

I've done that already :( still no bueno.
