Turbopack Error: reading the cell content failed

Turbopack version: v15.3.2

Error message:

Turbopack Error: reading the cell content failed

[baljir0901]

Hey! 👋 This error usually pops up when Turbopack’s internal cache or graph gets into a broken state — it’s been happening a bit more frequently with recent builds.

---

🧹 Quick Fix

Try clearing Turbopack’s build cache and restarting your dev server:

rm -rf .turbo .next
npm run dev
Or if you're using yarn:

bash
Copy
Edit
rm -rf .turbo .next
yarn dev
This resets the internal task graph and often resolves the issue where the error looks like:

javascript
Copy
Edit
Turbopack Error: reading the cell content failed
💡 Why this happens
It’s usually due to:

A crash during a previous dev session

Switching branches with incompatible builds

Stale data in .turbo not being invalidated correctly

Turbopack is still evolving, so these kinds of low-level task graph bugs do happen occasionally.

Hope this gets you back on track quickly!
Let me know if it keeps happening — happy to help further 🙌
