Enabling `sendDefaultPii` on server config triggers Next.js async parameter error

[daanvosdewael]

Is there an existing issue for this?

• I have checked for existing issues https://github.com/getsentry/sentry-javascript/issues
• I have reviewed the documentation https://docs.sentry.io/
• I am using the latest SDK release https://github.com/getsentry/sentry-javascript/releases

How do you use Sentry?

Sentry Saas (sentry.io)

Which SDK are you using?

@sentry/nextjs

SDK Version

9.31.0

Framework Version

Next 15.3.4

Link to Sentry event

No response

Reproduction Example/SDK Setup

In sentry.server.config.ts:

Sentry.init({
  debug: false,
  dsn: "",
  sendDefaultPii: true,
});

Steps to Reproduce

I probably copy / pasted too much when implementing the HttpClient integration on the client configuration and also added sendDefaultPii: true to the server configuration. So steps to reproduce:

1. add sendDefaultPii: true to sentry.server.config.ts
2. open any route in Next.js application in the browser

Expected Result

No error

Actual Result

The following Next.js error:

Error: Route "/" used `...params` or similar expression. `params` should be awaited before using its properties. Learn more: https://nextjs.org/docs/messages/sync-dynamic-apis
