`@sentry/nextjs` + `runtime = "edge"` causes `.next/app-build-manifest.json` not to be populated and builds to break

[nrgnrg]

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/nextjs

SDK Version

7.51.0

Framework Version

13.4.1

Link to Sentry event

No response

SDK Setup

import * as Sentry from "@sentry/nextjs";

Sentry.init({
 dsn: process.env.SENTRY_DSN || process.env.NEXT_PUBLIC_SENTRY_DSN,
 tracesSampleRate: 0.2,
 debug: false,
 replaysOnErrorSampleRate: 1,
 replaysSessionSampleRate: 0.1,
 integrations: [
 new Sentry.BrowserTracing(),
 new Sentry.Replay({
 maskAllText: true,
 blockAllMedia: true,
 }),
 ],
});

Steps to Reproduce

1. Setup a default template next project using the automatic setup and the app directory https://nextjs.org/docs/getting-started/installation
2. Used the wizard and set up "@sentry/nextjs" with the defaults for the next.config, client.config, edge.config, server.config

everything looks good at this point, next start works etc...

3. add export const runtime = "edge"; to the root layout

next start breaks because .next/app-build-manifest.json is now empty.

Removing withSentryConfig and returning the next config to the original default config or removing export const runtime = "edge"; gets the build working again and the manifest correctly populated.

Expected Result

Nothing should change by adding export const runtime = "edge";

Actual Result

// .next/app-build-manifest.json

{
 "pages": {}
}

Thanks for reporting this. I can reproduce. We will look at this with urgency.

Just to give a very small update here. We're currently talking to Vercel to maybe find a better solution to doing auto wrapping of server components. Currently it is very deeply nested in the SDK so we don't have a quick fix.

I do have a workaround for you however: You should be able to use the excludeServerRouts option to opt out of auto instrumentation for the routes relevant routes and then manually wrap them using wrapServerComponentWithSentry.

ok cool, thanks for the update @lforst 🙂

I'm struggling to get that workaround to work: the docs on excludeServerRoutes aren't clear on what I should put in there.

E.g. if my server component is at app/thing/[param]/other/page.tsx, what should go in excludeServerRoutes? I _think /thing/[param]/other based on the docs, but that doesn't seem to fix the issue 😬

@isaacseymour I think that should work. One question: Are you on windows?

[isaacseymour]

Nope! macOS

I've got this working by setting the excludeServerRoutes to [/.*/]`, but that does mean I have to manually wrap every server component and route handler 🙈
