Steps to Reproduce

While running the Sentry integration for a React Router v7 SSR app, Sentry reports a processing error for the field:

Name: contexts.trace.origin
Value: auto.navigation.react-router
Reason: invalid character '-'

This appears to be automatically generated by Sentry’s integration, not something set manually.

Expected Result

Sentry should accept the automatically generated contexts.trace.origin value from the React Router integration, or the integration should avoid producing invalid values

Actual Result

Sentry rejects the field value containing hyphens

Additional Context

No response

Thanks for reporting. Looks like a couple of invalid origin values slipped into the SDK (trace origin spec). We'll fix this in a bit.
