replace of undefined

Bug report

Describe the bug

Running into this error when running next build as I am trying to implement a dynamic SSG page. After generating the _next folder, there's a routes-manifest.json file. Inside the json file, there should be a dataRoutes key with array value, but for some reason, mine appears empty which caused this error. My pages directory looks like this.

pages
  |-- .[criteria]
         | -- blog.jsx

Stack trace:

TypeError: Cannot read property 'replace' of undefined
at routesManifest.dataRoutes.map.page (/mnt/c/Users/dgoh/Documents/GitHub/something/project/node_modules/next/dist/build/index.js:19:573)

I am using a custom server if that has anything to do with it.

Expected behavior

The project should be able to build without issues.

System information

• Version of Next.js: v9.5.3
• Version of Node.js: v12.19.0

getting the same error with version of Next.js: 9.5.1

Looks like the issue occurs only with dynamic routes
