Application breaks after updating @sentry/sveltekit to v7.91.0 #9979

Is there an existing issue for this?

I was following this issue #8925, and very existed to see support for CSP with #9969. But for some reason, the latest version crashes our application (500 internal server error).

• 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
