Autofix Details
Bugbot Autofix prepared fixes for both issues found in the latest run.
- ✅ Fixed: Stray backtick fences break entire CHANGELOG rendering
- Removed the stray 4-backtick sequences at lines 64 and 3802 that were creating an unintended code block wrapping the entire CHANGELOG content.
- ✅ Fixed:
getTraceDatachecks registration instead of actual context value- Changed from hasExternalPropagationContext() to getExternalPropagationContext() to check for actual context value, ensuring proper fallback to Sentry's scope-based propagation when no OTel span is active.

q: Could this be silently breaking for some users with a custom setup?

I can't really think of a use-case where it might. Typically if hasExternalPropagationContext evaluates true, the user has set up tracing via OTel, so there should be a spann
node-overhead report 🧳Note: This is a synthetic benchmark with a minimal express app and does not necessarily reflect the real-world performance impact in an application.

Span flush not awaited on client flush/close
Medium Severity
The flush and close event handlers use void to discard the promises from _spanProcessor?.forceFlush() and _spanProcessor?.shutdown(). Since client.emit('flush') is synchronous and doesn't await handler return values, Sentry.flush() and Sentry.close() resolve before the OTel span processor finishes exporting spans. This can cause data loss in serverless or CLI-exit scenarios where the process ends right after flushing.

Added `otlpIntegration` at `@sentry/node-core/light/otlp` for users who manage their own OpenTelemetry setup
and want to send trace data to Sentry without adopting the full `@sentry/node` SDK.
```js
import { NodeTracerProvider } from '@opentelemetry/sdk-trace-node';
import * as Sentry from '@sentry/node-core/light';
import { otlpIntegration } from '@sentry/node-core/light/otlp';
const provider = new NodeTracerProvider();
provider.register();
Sentry.init({
dsn: '__DSN__',
integrations: [
otlpIntegration({
setupOtlpTracesExporter: true, // Export OTel spans to Sentry via OTLP (default: true)
setupPropagator: true, // Propagate sentry-trace/baggage headers (default: true)
captureExceptions: false, // Capture span.recordException() as Sentry errors (default: false)
}),
],
});
```
The integration links Sentry errors to OTel traces, exports spans to Sentry via OTLP, and propagates
`sentry-trace`/`baggage` headers for distributed tracing.
