❌ `wrangler dev` - `✘ [ERROR] write EOF`

Wrangler doesn't support the Bun runtime: running wrangler dev under Bun gives a write EOF error. Your code runs in the Workerd runtime anyway, so use Node.js to run wrangler itself (Bun is fine as a package manager). If the error persists under Node, it's a different problem.
