+##### `next` version
+
+The `next` version is 14.1.0, as we get the following error with 15.1.2 and above when accessing `/[username]` pages on Vercel:
+```
+Cannot find module 'next/dist/compiled/source-map'
+Require stack:
+- /var/task/node_modules/next/dist/compiled/next-server/server.runtime.prod.js
+- /var/task/web/___next_launcher.cjs
+Did you forget to add it to "dependencies" in `package.json`?
+Node.js process exited with exit status: 1. The logs above can help with debugging the issue.
+```
+TODO: investigate, find a fix and upgrade.
