Error: Failed to collect page data for

I encountered a strange issue 2-3 days ago. I started receiving the following error:

SyntaxError: Unexpected identifier '#Y'

The route in question hadn't been modified in over 21 days, so it seemed unlikely that it was the source of the error. After some debugging, I decided to delete the route and see what happened. This led to errors on other routes, so I continued deleting them. After removing 5 routes, I began to suspect that the issue wasn't with the routes themselves. I eventually deleted most of them, but the same error persisted on routes that had been in production for over 3 months.

I found some users on Google experiencing the same error, even when starting a new project from scratch with a Next.js template. This made the situation even more puzzling. I then reverted to a commit that was in production 1-2 months ago, but the error remained. Clearly, something external to my app is causing this issue.

Creating a new project isn't an option since this one has been in production for over 6 months, and I need to deploy new adjustments today. I've performed a clean install on all branches and tests, deleted node_modules, and removed package-lock.json.

Does anyone have any idea what might be causing this?

Hi ! Welcome to the Vercel Community 😄

Thanks for the detailed description. Let's tackle this strange issue with some quick checks:

Node.js Version: Ensure consistency with an .nvmrc file:

 echo "18.17.0" > .nvmrc  # Replace with your project's Node version

Next.js Version: Try downgrading:

 npm install next@14.1.0npm install next@14.1.0

Babel: Check for custom configs interfering with Next.js.
TypeScript: Verify tsconfig.json compatibility with your Next.js version.
ESLint: Temporarily disable to isolate the issue:

 mv .eslintrc.json .eslintrc.json.bakmv .eslintrc.json .eslintrc.json.bak

Next.js Cache: Clear it:

 rm -rf .nextrm -rf .next

Dependencies: Update all:

 npx npm-check-updates -u && npm installnpx npm-check-updates -u && npm install

File Encoding: Ensure UTF-8 without BOM for all files.
Environment Variables: Review, especially in API routes.
Experimental Flag: Add to package.json scripts:

 "dev": "node --experimental-vm-modules node_modules/next/dist/bin/next dev""dev": "node --experimental-vm-modules node_modules/next/dist/bin/next dev"

(Do the same for "build" and "start" scripts)

If these don't work, try creating a minimal reproduction.

Good luck, and let us know how it goes!
