Confusing error when trying to deploy Rust docs

[rikhuijzer]

I'm quite sure that the

Artifact could not be deployed. Please ensure the content does not contain any hard links, symlinks and total size is less than 10GB.

is also triggered when there is no index.html file.

Can you point us at a workflow run maybe where you see this error?

[rikhuijzer]

Yes. Thanks for reaching out, @yoannchaudet, and my apologies for not providing anything to work with. To make it up to you all, I put in some extra effort and made a minimal reproducible example at https://github.com/rikhuijzer/deploy-pages-mwe.

The repository contains a minimal Rust project and attempts to deploy the docs via actions/upload-pages-artifact@v3 and actions/deploy-pages@v4.

This is the full workflow, which should work for any simple Rust project:

name: docs

on:
  push:
    branches:
      - main
  pull_request:
  workflow_dispatch:

jobs:
  build:
    runs-on: ubuntu-latest
    timeout-minutes: 10
    steps:
      - name: Checkout repository
        uses: actions/checkout@v4

      - name: Setup Stable Rust
        uses: dtolnay/rust-toolchain@v1
        with:
          toolchain: 'stable'

      - name: Build docs and manually add an index.html file
        run: |
          cargo doc --all --no-deps
          echo '<meta http-equiv="refresh" content="0; url=mwe">' > target/doc/index.html

      - uses: actions/upload-pages-artifact@v3
        if: ${{ github.event_name != 'pull_request' }}
        with:
          path: './target/doc'
          retention-days: '1'

  deploy:
    # Separate step to keep the permissions separated.
    needs: build
    if: ${{ github.event_name != 'pull_request' }}
    permissions:
      contents: read
      pages: write
      id-token: write
    environment:
      name: github-pages
      url: ${{ steps.deployment.outputs.page_url }}
    runs-on: ubuntu-latest
    steps:
      - id: deployment
        uses: actions/deploy-pages@v4

This is the error:

In another repository, I could easily fix the error by switching to deploying the pages via a gh-pages branch instead of actions/deploy-pages (For more details about that see https://github.com/poweranalyses-org/rmathlib/commits/main/ and scroll down a bit to see the failing CI runs near commit 2212240227088ce15d283851e4007aa3c14efb75).

5 directories, 42 files

I also manually confirmed via ls -ahlv that none of these files seems to be a hard link or a symlink. Also, the file size is only about 1 MB which is well below 10 GB that the error talks about.

@rikhuijzer Thanks for spending the time to get some details!

We do a bit more validation than the error message implies (will look into fixing that so it's clear what's going on).

Here is what's tripping your deployment:

Tarball contains file without 'read other' permission ./.lock

We talk about permissions and provide some ways to fix that in:

https://github.com/actions/upload-pages-artifact?tab=readme-ov-file#file-permissions

I hit this too; luckily I found this issue since the error message is not helpful.

The simplest fix appears to be just to delete the .lock file:

rm target/doc/.lock

I'm facing the same issue. How were you able to see this error? It could help me work out what's wrong with my deployment.

all I see is:

I'm not sure if it's because I've not specified a token?

I'm trying to deploy an Astro site.
