Sentry transport requires a DSN

Error message

Sentry transport requires a DSN

What it means

Input validation in the Sentry transport factory: a transport was requested without a DSN (the sentry.io project endpoint URL). Sentry cannot route events without one, so the factory refuses to build rather than silently dropping every event; the caller must supply a DSN or skip Sentry initialization.

Solutions

1. Provide the Sentry DSN via the standard env/config channel before initializing the transport
2. Skip Sentry init entirely when no DSN is configured (crash reporting becomes a no-op)
3. Guard DSN presence at config-load time so the transport is never constructed DSN-less
