Lint deploy issue with source maps

Help

Hello everyone!

I’m having the following build error when trying to deploy my website which has been deployed several times in the last months with no issues.

Failed to compile.
./__next_data_cache_handler.js:1:162
Type error: Parameter 'a' implicitly has an 'any' type.

 ELIFECYCLE  Command failed with exit code 1.
Error: Command "pnpm run build" exited with 1

The thing is I cannot replicate this behaviour in my local environment, and I’m kinda lost here. I tried to update Next.js to the latest version (just in case) but the same error happens.

It’s strange because I don’t have the productionBrowserSourceMaps: true flag in my next.config.js but still is building some source maps files?

Has someone ever seen something like this?

Thanks in advance!

Cheers,
Fernando

Facing the same issue.

We regret any inconvenience you may have experienced.

Edited: we are investigating this.

Nope. Still the same…

Alright we are investigating this. You can revert the Environment variable meanwhile.

Thanks man! appreciate it

I’m having the same issue here as well.

Found a workaround

In your tsconfig:

  1. add "exclude": ["node_modules", ".next", "out", "build"]
  2. remove ".next/types/**/*.ts" from “include”

Hi,

We rolled back a changes. Could you try again and let us know if you are still experiencing the issue?

I just tried a few minutes ago with the env var you suggested and for me it worked! I will try again though without the env var to see if it works as well! Will let you know! Thanks!

11

Yes you should remove the environment variable to unpin CLI version and receive future updates.

12

Yes, now it works! With Vercel CLI 37.7.0 works fine! Thanks for the super fast response :heart_hands:

Amazing, Thanks for confirming!
