• I am using the latest SDK release https://github.com/getsentry/sentry-javascript/releases

How do you use Sentry?

Reproduction Example/SDK Setup

https://github.com/wladpaiva/sentry-gh-error

Steps to Reproduce

1. add a file to the root of the project that sentry wont have permissions
2. run nextjs on CI

Expected Result

No error at all

Actual Result

Getting this error of permissions denied when running a nextjs with playwright on CI ever since I updated sentry package from 9.6.0 to 9.13.0. Tried the 9.14 but same issue.

Hi, I don't think the SDK is reading random files. The SDK is trying to read instrumentation files and .git related files but I don't think anything else. I fear this might be a turbopack problem and not a Sentry problem. Would you mind raising it upstream in the Next.js repo?

Also, what kind of file without read perms are you creating?

[wladpaiva]

Those are postgres files that are created during the CI setup. I suppose I could raise it to the nextjs team but it's likely they will reject it since nextjs works fine without the sentry installed.

I created this PR on the reproduction repo only removing sentry from the stack and you can see the gh action works as expected
wladpaiva/sentry-gh-error#1

Another point is that it used to work fine with 9.6.0

Added stdout and here is details of the error

I think it's still worth asking. We are not doing anything too unorthodox and it is very well a potential Next.js issue if it fails to compile an ordinary package! I'll ping them.
