[Sentry] Express is not instrumented. This is likely because you required/imported express before calling `Sentry.init()`

SDK Setup

// main.ts
import * as Sentry from "@sentry/node";
import { nodeProfilingIntegration } from "@sentry/profiling-node";
Sentry.init({
	serverName: "auth-service",
	dsn: process.env.SENTRY_DSN,
	environment: process.env.NODE_ENV,
	enabled: true,
	debug: process.env.NODE_ENV !== "production",
	integrations: [Sentry.httpIntegration(), Sentry.expressIntegration(), nodeProfilingIntegration()],
	// Set tracesSampleRate to 1.0 to capture 100%
	// of transactions for performance monitoring.
	// We recommend adjusting this value in production
	tracesSampleRate: 1.0,
	beforeSend(event, hint) {
		const error = hint.originalException as Error;
		if (error?.message?.match(/database unavailable/i)) {
			event.fingerprint = ["database-unavailable"];

		// Modify or drop the event here
		if (event.user) {
			// Don't send user's email address
			event.user.email = undefined;
		}

		return event;
	},

	// Called for transaction events
	beforeSendTransaction(event) {
		// Modify or drop the event here
		if (event.transaction === "/unimportant/route") {
			// Don't send the event to Sentry
			return null;
		}
		return event;
	},
	beforeBreadcrumb(breadcrumb, hint) {
		// Check if the breadcrumb has sensitive data like user email
		if (breadcrumb.data?.["user"]?.email) {
			// Remove the user email from the breadcrumb
			breadcrumb.data["user"].email = undefined;
		}
		return breadcrumb;
	},
	includeLocalVariables: true,
	attachStacktrace: true,
});

Steps to Reproduce

1. install NX
2. Install NX's express
3. run nx run --target=serve

I did right as you suggested it in your docs. Imprted and initialised Sentry first thing first. But still, it's not working

Expected Result

Do not have [Sentry] Express is not instrumented. This is likely because you required/imported express before calling Sentry.init() message, and

Actual Result

Having error message: [Sentry] Express is not instrumented. This is likely because you required/imported express before calling Sentry.init() message, and

Strange... I did some code refactoring, and didn't touch this part I shared at all.. somehow I'm not having this error anymore. I will close this issue for a bit, if I encounter it again, I'll reopen it

[amiranvarov]

Isse came back again, I have no idea why. I didn't change anything. tried to update to latest Sentry, didn't help. Tried to nuke node_modules. lock file and everything, still didn't work. This is some weird mystery...

Hi there,

Things changed in v8 a bit, most integrations are now automatically added and you no longer have to take care of those (with the exception of nodeProfilingIntegration in your example).

We recommend going through the migration guide here. You can use npx @sentry/migr8@latest to take care of it for you, or follow the steps to manually set it up here.

In your particular example, could you try removing Sentry.httpIntegration() and Sentry.expressIntegration() and report back?

[amiranvarov]

hey, thanks for getting back @andreiborza! I did follow the migration guide, and used npx @sentry/migr8@latest right from the start. But no, it didn't help.

As you suggested, i removed Sentry.httpIntegration and Sentry.expressIntegration() it didn't help. Then i removed all of the integrations, didn't help either. still getting this message.
