SDK Setup

Sentry.init({ dsn: "https://xxxxx.ingest.sentry.io/xxxxx", enableTracing: false, sampleRate: 0, tracesSampleRate: 0, autoSessionTracking: false, tracePropagationTargets: ["example.com"], });

Steps to Reproduce

See above code

Expected Result

Sentry should simply be processing server exceptions and logging them. No other 'features' should be enabled.

Actual Result

I am trying to use Sentry to capture server errors but I don't know how to prevent it from just taking over. It's adding sentry-trace and baggage headers to HTML pages, and there seems to be no way to disable it. Things seem opt-out when they should be opt-in.

From what I can tell the tracePropagationTargets setting should allow me to disable it, but it doesn't seem to work. I've set tracePropagationTargets to example.com but it's still sending out those headers with all requests.

I am caching my HTML pages at the edge which would probably make these headers useless anyways.
