I suspect this is something rather obvious to someone more familiar with the JavaScript build tools: <img width="1029" alt="image" src="https://user-images.githubusercontent.com/34410036/171092258-dcadd2c0-eeb1-48ae-a05a-b4ae3dcc7715.png"> when running `npm run dev`. `npm run serve` allows cell execution (as expected) -- I'm not exactly sure why this throws during `dev`.
