[webPlayer7]

Is there an existing issue for this?

• I have checked for existing issues https://github.com/getsentry/sentry-javascript/issues
• I have reviewed the documentation https://docs.sentry.io/
• I am using the latest SDK release https://github.com/getsentry/sentry-javascript/releases

How do you use Sentry?

Sentry Saas (sentry.io)

Which SDK are you using?

@sentry/node

SDK Version

8.51.0

Framework Version

Express v5

Link to Sentry event

No response

Reproduction Example/SDK Setup

import * as Sentry from '@sentry/node'


Sentry.init({
    dsn: process.env.SENTRY_DSN,
    environment: process.env.SENTRY_ENVIRONMENT,
    release: appVersion,
    tracesSampleRate: 0.0,
})

console.log(`================================`)
console.log(`****** Sentry Initialized ******`)
console.log('================================')

export { Sentry }

Above is my sentry instrument js and I import that file in the index.js like below
import { Sentry } from './instrument.js'

I confirmed it gets the correct env values. My express version is v5. And I use esm mode to import so I run this command to import instrument.js
nodemon --import ./build/instrument.js build/index.js

When I use express v4, it worked but after migrate it shows sentry warning again

[1] [Sentry] express is not instrumented. Please make sure to initialize Sentry in a separate file that you --import when running node, see: https://docs.sentry.io/platforms/javascript/guides/express/install/esm/.

Steps to Reproduce

1. Sentry init in instrument.js
2. Import instrument.js in index.js
3. Run script in esm mode , use --import flag to import

Expected Result

There should no sentry warning

Actual Result

[1] [Sentry] express is not instrumented. Please make sure to initialize Sentry in a separate file that you --import when running node, see: https://docs.sentry.io/platforms/javascript/guides/express/install/esm/.

Hi, thanks for writing in! You're getting this warning because Express 5 is not yet supported by Opentelemetry's Express instrumentation. See open-telemetry/opentelemetry-js-contrib#2435

For the moment, you will not get Express spans in your traces. As for error capturing, I'm not a 100% sure but I think it should work (tagging @AbhiPrasad or @timfish to confirm).

Error monitoring should work fine. I updated the tracking issue here: #13674 to show the current state right away, hopefully making this a bit clearer. I'll close this as a duplicate, you can follow along in the linked issue! I also opened a docs PR to call this out for future readers: getsentry/sentry-docs#12465
