Reproduction Example/SDK Setup
// Sentry init
Sentry.init({
dsn: process.env.NEXT_PUBLIC_SENTRY_DSN,
environment: process.env.NEXT_PUBLIC_SENTRY_ENVIRONMENT,
tracesSampleRate: process.env.NEXT_PUBLIC_SENTRY_TRACES_SAMPLE_RATE_FLOAT
? parseFloat(process.env.NEXT_PUBLIC_SENTRY_TRACES_SAMPLE_RATE_FLOAT)
: 0.01,
});// Next config using withSentryConfig
module.exports = withSentryConfig(nextConfig, {
org: 'orgName',
project: 'products',
// Only print logs for uploading source maps in CI
silent: !process.env.CI,
// Upload a larger set of source maps for prettier stack traces (increases build time)
widenClientFileUpload: true,
// Hides source maps from generated client bundles
hideSourceMaps: true,
// Automatically tree-shake Sentry logger statements to reduce bundle size
disableLogger: true,
// also fails without this whole section being present, and it also used to work without it being there at all
sourcemaps: {
// Ensure sourcemaps are left behind by Sentry so that next-sitemap can use them
deleteSourcemapsAfterUpload: false,
},
});Steps to Reproduce
Set up a Next project with Sentry integration.
Add next-sitemap as a dependency, e.g. pnpm add next-sitemap / npm install next-sitemap.
Add a next-sitemap.config.js file:
module.exports = {
siteUrl: 'https://www.example.com',
generateIndexSitemap: false,
sitemapSize: 1000000,
};Add a postbuild step in package.json:
"postbuild": "next-sitemap",Set a valid SENTRY_DSN env variable value and run pnpm build / npm build.
Expected Result
Postbuild step succeeds in generating the sitemap -- this is working on v8.48.0
Actual Result
Error in postbuild step:

There seems to be one recent change in the area, from the title it seems to be specifically for sveltekit but I haven't dug into it: #14963

Hi, I cannot reproduce what you are describing. Would you mind sharing a reproduction repo we could pull to look at this?

Apologies, when trying to narrow this down further it seems like we also upgraded
@sentry/webpack-pluginfrom 2.23.0 to 3.0.0, and that may be actual cause of the issue. I'll file a separate issue when I can confirm this.
