Sentry causes Next.js standalone to copy entire repo into build output #18004

Description

@BTOdell

Is there an existing issue for this?

How do you use Sentry?

Sentry Saas (sentry.io)

Which SDK are you using?

@sentry/nextjs

SDK Version

10.21.0

Framework Version

Next 16.0.0

Link to Sentry event

No response

Reproduction Example/SDK Setup

https://github.com/BTOdell/sentry-nextjs-standalone-bug

Steps to Reproduce

  1. Set Next.js build output to 'standalone'
  2. Import Sentry SDK from instrumentation.ts (don't even need to configure Sentry in next.config.ts)

Expected Result

Next.js standalone build output should only contain the minimal files needed to run the app

Actual Result

Standalone output directory contains copy of the entire repository / project

Additional Context

Confirmed that this bug does not happen with Next 15.4.4 with @sentry/nextjs v9 nor v10.
Likely a compatibility issue with Next 16?

May be related to #18001, but I'm not getting a build error - just incorrect build output.

                Sentry causes Next.js standalone to copy entire repo into build output #18004

                Description

                @BTOdell

                Is there an existing issue for this?

                How do you use Sentry?

                Sentry Saas (sentry.io)

                Which SDK are you using?

                @sentry/nextjs

                SDK Version

                10.21.0

                Framework Version

                Next 16.0.0

                Link to Sentry event

                No response

                Reproduction Example/SDK Setup

                https://github.com/BTOdell/sentry-nextjs-standalone-bug

                Steps to Reproduce

                1. Set Next.js build output to 'standalone'
                2. Import Sentry SDK from instrumentation.ts (don't even need to configure Sentry in next.config.ts)

                Expected Result

                Next.js standalone build output should only contain the minimal files needed to run the app

                Actual Result

                Standalone output directory contains copy of the entire repository / project

                Additional Context

                Confirmed that this bug does not happen with Next 15.4.4 with @sentry/nextjs v9 nor v10.
                Likely a compatibility issue with Next 16?

                May be related to #18001, but I'm not getting a build error - just incorrect build output.
