> **Windows:** `npm run dev` may show a Bad Gateway error if Vite exits with a `C:\Program` path error. Run the dev stack directly instead:

Hmm npm run dev simply wraps node --env-file-if-exists=.env scripts/dev-with-automation.mjs command

Unclear to me why one fails but the other works

Is there a workaround that allows npm run dev to work? Because once we release the npm package it would be great if they could use it directly

That is the thing. I got this error for the first time I used agent canvas last week. And then earlier this week it worked great. and then i got bad getaway again!

@OpenHands can you investigate the codebase. What would need to change so windows, mac, and linux can run without running into bad getaway at all so that a user after npm install can just run npm run dev
