Fig plugin shows startup errors and doesn't do anything

[oliversturm]

I just installed the Fig plugin from the dashboard. Ran fig source in a terminal and this is what I see:

> fig source

✅ Dotfiles sourced!

Same output appears if I run a new shell.

Tried to press Alt-k and nothing happens, but I guess the initialization fails so that's not surprising.

Running zsh 5.9 on a Mac. Not sure which other details might be useful, let me know.
