Edge Functions deploy: 400 "Bundle generation timed out" (Dashboard/API)

# Bug report - [x] I confirm this is a bug with Supabase, not with my own application. - [x] I confirm I have searched the [Docs](https://docs.docs.supabase.com), GitHub [Discussions](https://github.com/supabase/supabase/discussions), and [Discord](https://discord.supabase.com). ## Describe the bug Deploying an Edge Function via the Supabase Dashboard (REST API) fails with HTTP **400** and body: `{"message":"Bundle generation timed out"}` The request is: `POST https://api.supabase.com/v1/projects/<PROJECT_REF>/functions/deploy?slug=smart-action` The function entrypoint is a **single very large** `index.tsx` file (**~9176 lines**). Hypothesis: server-side bundling (dependency graph + transpile/bundle) exceeds the platform’s bundle-generation timeout. The error message does not indicate whether the timeout is due to code size, dependency resolution, or an external registry/CDN slowdown. Related report: https://github.com/supabase/supabase/issues/41771 1 month ago I can deploy this function without any problem. ## To Reproduce Steps to reproduce the behavior: 1. Create or update an Edge Function with slug `smart-action` (or equivalent) whose main handler lives in a **monolithic** `index.tsx` on the order of **~9000+ lines**, with a non-trivial import graph (typical app/server-style imports). 2. Deploy from the **Supabase Dashboard** (or the same deploy API the Dashboard uses). 3. Observe the network request to `POST /v1/projects/<myProject>/functions/deploy?slug=smart-action` 4. Response: **400 Bad Request** with `{"message":"Bundle generation timed out"}`. **Minimal repro (ideal for maintainers):** a small public repo with a synthetic `index.tsx` of comparable size (or generated lines) and similar import pattern, deployed to a test project — I can provide this if needed once I strip secrets. ## Expected behavior Either: - The function **deploys successfully** within documented limits, or - The API returns a **clear, actionable error** (e.g. bundle size / step …
