setupNestErrorHandler does not work properly within a NestJS + GraphQL application

[Blargel]

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

8.2.1

Framework Version

@nestjs/core@10.3.8, @nestjs/graphql@12.1.1

Link to Sentry event

No response

SDK Setup

Sentry.init({
 dsn: [redacted],
 integrations: [nodeProfilingIntegration()],
 tracesSampleRate: 1.0,
 profilesSampleRate: 1.0,
})

async function bootstrap(): Promise<void> {
 const app = await NestFactory.create(AppModule)
 Sentry.setupNestErrorHandler(
 app,
 new BaseExceptionFilter(app.getHttpAdapter()),
 )
 await app.listen(config.port)
}

Steps to Reproduce

1. Clone this repo: https://github.com/Blargel/sentry-nestjs-graphql-test
2. npm install
3. Open src/main.ts and change the DSN const to something valid.
4. npm start
5. In a web browser, go to http://localhost:3000/
6. Observe that an error is raised and reported to Sentry correctly. This is a regular HTTP endpoint with an error and works as expected.
7. In a web browser, go to http://localhost:3000/graphql
8. This will open a GraphQL explorer. I believe it defaults to the correct query for testing but if not, the correct test query is query {hello}.
9. Execute the query by pressing the play button in the top middle of the GraphQL explorer.
10. Observe that a strange TypeError is raised and the original error is not sent to Sentry correctly.

Expected Result

The GraphQL error should also be reported to Sentry without raising the strange TypeError.

Actual Result

No error reported in Sentry and the following error is thrown:

TypeError: response.status is not a function

Thanks for reporting this @Blargel!

It looks like GraphQL does not work well with BaseExceptionFilter. (Ref: nestjs/nest#5958 (comment))

I have tried to update your setup as,

async function bootstrap(): Promise<void> {
 const app = await NestFactory.create(AppModule)
 Sentry.setupNestErrorHandler(
 app,
 new ExternalExceptionFilter(),
 )
 await app.listen(config.port)
}

And it seemed to work.

Could you check if that resolves the issue?

If so we may need to add a note in the docs about this.

Hmmmm, that works in the test repo I put in my bug report, but it's not working on my actual application. The same TypeError as before is still being thrown. Let me get back to you on this when I figure out what's different.

[Blargel]

Oops, nevermind it works. Maybe something weird got cached. Anyways, that does fix my issue then. Thanks! Should I leave this open to track documentation updates?

Great that we found a solution - I'll close the issue, users can (hopefully) still find it if they search! 🙏
