AMP First Pages: Could not find files for /xxx in .next/build-manifest.json

[ka2jun8]

Bug report

Describe the bug

When AMP first pages are accessed, the following error statement outputs.
Could not find files for /xxx in .next/build-manifest.json.

These AMP pages can be viewed.

To Reproduce

1. cd /zeit/next.js/examples/amp-first
2. npm i
3. npm run build
4. npm run start
5. Go to 'localhost:3000'
6. See following error in your console

> next start

ready - started server on http://localhost:3000
Could not find files for / in .next/build-manifest.json

Expected behavior

No error outputs.

Screenshots

None.

System information

• OS: macOS
• Browser (if applies) Chrome
• Version of Next.js: v9.5.3
• Version of Node.js: v13.14.0

Additional context

This error will be called in getPageFiles here.
getPageFiles will be called in getDocumentFiles here.
getDocumentFiles is called when rendering all pages that use _document.
So all pages might pass this function.

But I found that AMP First Pages was not included in build-manifest.json's pages (PR).
And, when AMPState ampFirst is true, the amp page files were excluded by render.tsx.
However, This PR seems to be removed that feature and caused the error.

It may be roughly solved the following way in _document.tsx.

before:

    const files: DocumentFiles = getDocumentFiles(
      this.context.buildManifest,
      this.context.__NEXT_DATA__.page
    )

after:

    const files: DocumentFiles = inAmpMode ? {
      sharedFiles: [],
      pageFiles: [],
      allFiles: [],
    } : getDocumentFiles(
      this.context.buildManifest,
      this.context.__NEXT_DATA__.page
    )

Hi! I am having a similar bug setting up AMP first pages. Is there any resolve for this?

Error message: /xxx in .next/build-manifest.json
Here is what my build-manifest.json file looks like.
It seems that the AmpFirstPages isn't being populated properly...or at all
I would really love some help figuring this out please! Thank you!

I'm still having this problem.. what was the solution?
My log: Could not find files for /[slug] in .next/build-manifest.json

My Next.js version is 9.5.4

Hello @ka2jun8 ! Myabe you know this one. I have next: 10.0.7 and this just popped up:

./src/components/header/index.tsx
Module not found: Can't resolve '/Users/app/node_modules/next/node_modules/@babel/runtime/helpers/esm/taggedTemplateLiteral' in '/Users/app/src/components/header'
Could not find files for / in .next/build-manifest.json
Could not find files for / in .next/build-manifest.json

Any solutions?

@nicolasguasca1

Sorry, I did not know the solution.

I tried following operations again to reproduce your issue.
But I could not catch the error 'Could not find...'.
So I think it is not occurred by next.js 10.0.7.

1. cd /vercel/next.js/examples/amp-first
2. vi package.json # change next.js version to "10.0.7"
3. npm i
4. npm run build
5. npm run start
6. Go to 'localhost:3000'

How about removing .next and node_modules and try it again?

[nicolasguasca1]

Thank you! I did upgrade to next 10.1.3 remode node modules and yanr.lock. After that I did yarn install again and everything went well :)

+1 with Next v11.0.1 and not only with AMP pages, but occasionally with any page in dev mode which is accessed for the first time.

Heads up - I've managed to fix this by updating webpack via

yarn add webpack --dev
