Having the same issue since yesterday, when I updated the plugin. After the error message appears, when invoking MagmaDelete, the same message keeps popping up, forcing me to restart nvim.

I have the same issue You can go back to commits before edfd16e (which is the commit that broke it) The newest commit before that one was: edf60f0 so you can just go to autoload/plugged/magma-nvim and run git checkout edf60f0b809c88dab3a4ea492e0dcf80fc00af5b

So... I found a problem, basically sometimes it was trying access a key in self.outputs while it was empty, so I just made it check if key is in the dictionary before trying to access it and that fixed the issue

Solved in 395b48e2e202d82fca76c15d2dcd8785c125d686 (via #58). Thanks, @MrBober!
