This is my next.config.js

const { withSentryConfig } = require("@sentry/nextjs");

const {
  NODE_ENV,
  SENTRY_AUTH_TOKEN,
  VERCEL_GITHUB_COMMIT_SHA,
  NEXT_PUBLIC_SENTRY_PROJECT
} = process.env;

const SENTRY_ORG = "...";
const SENTRY_PROJECT = NEXT_PUBLIC_SENTRY_PROJECT ||  `...`;

const moduleExports = {
  productionBrowserSourceMaps: false,
  async headers() {
    return [
      {
        // matching all API routes
        source: "/api/:path*",
        headers: [
          {
            key: "Access-Control-Allow-Headers",
            value: "sentry-trace"
          }
        ]
      }
    ];
  },
  eslint: {
    // Warning: Dangerously allow production builds to successfully complete even if
    // your project has ESLint errors.
    ignoreDuringBuilds: true
  }
};

const SentryWebpackPluginOptions = {
  authToken: SENTRY_AUTH_TOKEN,
  ignore: ["node_modules"],
  include: ".next",
  release: VERCEL_GITHUB_COMMIT_SHA,
  org: SENTRY_ORG,
  project: SENTRY_PROJECT,
  silent: NODE_ENV === "production" ? false : true
};

module.exports = withSentryConfig(moduleExports, SentryWebpackPluginOptions);

Expected Behavior

The app should run normally as it does with Next 11.1.0

To Reproduce

This is a private repo. And I haven't been able to reduce it to minimum code to reproduce this issue.
But downgrading from Next 12 to Next 11.1.0 makes it runs fine

Closing as a duplicate of #30349

[hoodwink73]

Oh well, will try without Sentry.

Hopefully, the issue gets resolved on the sentry repo.
