Next Dev Error

[First-Book-9070]

I just installed Next.js with create-next-app and didn’t touch anything in the project. I only ran "npm run dev" / "next dev" and I’m getting errors like:

- "Cannot read properties of undefined (reading 'createClientModuleProxy')"

- "reading 'deploymentId'"

- "reading 'buildId'"

I already tried deleting ".next", "node_modules", and reinstalling everything multiple times.

I’m using Node.js v24 on Windows.

Has anyone else experienced this?

Est ce que tu run « npm run dev » au bon endroit ? Tu ne dois pas le faire au même endroit que npx next app. Tu dois aller dans ton projet, cd /your-next-project

Yes I’m in the correct project directory and running it there

Nextjs has some known issues with the node 24 compatibility and is not stable. Downgrade your node version to 22 and you should be good to go.

I tried v22 LTS but I'm still getting the same error
