What

Make orchestrion diagnostics-channel instrumentation the default in @sentry/node and remove the experimentalUseDiagnosticsChannelInjection() opt-in.

Why

The channel-based instrumentations shipped opt-in in v10. Making them the default in v11 unlocks instrumentation at run and build time.

Removal of the vendored OTel/IITM code is intentionally out of scope; it is tracked separately as follow-up.

Closes: #22345

Make orchestrion diagnostics-channel injection the default in `@sentry/node`
and remove the `experimentalUseDiagnosticsChannelInjection()` opt-in.

`Sentry.init()` now installs the channel-injection module hooks unconditionally
when span recording is enabled, so the opt-in function, its loader indirection,
and the name-based OTel->channel integration swap are gone. The self-selecting
`dataloader` and `knex` integrations pick the channel path automatically now
that `isOrchestrionInjected()` is true by default.

Redis stays a composite integration: the native diagnostics-channel subscribers
(node-redis >=5.12, ioredis >=5.11, batches) plus the orchestrion subscribers
for the older ranges, all sharing the node cache `responseHook`. The vendored
OTel patchers only run on runtimes without `tracingChannel` (Node <18.19).

BREAKING CHANGE: `experimentalUseDiagnosticsChannelInjection()`,
`diagnosticsChannelInjectionIntegrations()`, `isDiagnosticsChannelInjectionEnabled()`
and `applyDiagnosticsChannelInjectionIntegrations()` are removed from
`@sentry/node`. Channel-based instrumentation is now always on; no opt-in call
is needed.

// No-op otherwise.
return applyDiagnosticsChannelInjectionIntegrations(integrations, options);
export function getDefaultIntegrations(_options: Options): Integration[] {
return [...getDefaultIntegrationsWithoutPerformance(), awsIntegration(), awsLambdaIntegration()];

AWS serverless drops performance integrations

High Severity

Removing applyDiagnosticsChannelInjectionIntegrations from getDefaultIntegrations leaves @sentry/aws-serverless defaults without any auto-performance integrations when tracing is on. Sentry.init() still registers orchestrion hooks, but the slim default list never includes channel subscribers such as postgresIntegration() or expressIntegration(), so Lambda apps lose DB and framework spans that the opt-in path used to append.

View base workflow run

Forward build-resolved tracingHooksDir in @sentry/nextjs server init so bundled
pnpm apps load the channel-injection hook.
Update span origins to orchestrion values (koa, hapi, nestjs, firebase functions)
and add error.type to errored express request_handler spans.
Skip preload and bring-your-own-OTel apps (node-express-cjs/esm-preload,
node-otel-sdk-node, node-otel-custom-sampler); fixme AI (ai@v3), trpc, and
firebase functions tests pending follow-ups.

Next build injection still opt-in

High Severity

Default @sentry/node integrations now rely on orchestrion diagnostics channels, but withSentryConfig still defaults _experimental.useDiagnosticsChannelInjection to false, so the webpack/Turbopack transform usually does not run. Server bundles may never emit channel events while the SDK only subscribes to the channel path, silently dropping library auto-instrumentation for typical Next apps.

Node 18 loses auto tracing

Medium Severity

Default integrations now delegate to orchestrion channel subscribers that no-op when diagnostics_channel.tracingChannel is missing (Node before 18.19), while OTel instrumentations are no longer wired from those factories. With engines.node still >=18, supported 18.0–18.18 runtimes can lose mysql, express, and similar auto-instrumentation entirely.
