Artifact download fails with ambiguous "Error: Not Found"

I created Build and Deploy workflows where the Deploy workflow retrieves artifacts from the Build workflow. This excellent action is working successfully in several repos, but in one instance there is an issue downloading artifacts from the upstream workflow. This Build workflow is comprised of 6 separate jobs where the first 5 run on macos-latest, and the 5th runs on a Windows 10 self-hosted action runner. The Build jobs are all successful and each collects an artifact.

The Deploy workflow runs on the same Windows 10 self-hosted action runner. When this workflow runs, it fails to download the artifacts, giving an ambiguous error message, “Error: Not Found”. It does not indicate the workflow or artifacts cannot be found, and I’ve verified they exist.

The action is defined in the Deploy workflow as follows.

- name: Download Build Artifacts uses: dawidd6/action-download-artifact@v2 with: github_token: ${{ secrets.MY_TOKEN }} workflow: Build.yml commit: ${{ env.ARTIFACTS_SHA }} path: ${{ env.ARTIFACTS_DIR }}

The output from the workflow is reported as follows.

Run dawidd6/action-download-artifact@v2 with: github_token: *** workflow: Build.yml commit: e945cf6d4eb18ac65e4de8767ac85fc1ffffffff path: artifacts/e945cf6d4eb18ac65e4de8767ac85fc1ffffffff workflow_conclusion: success repo: MyOrganization/MyProject env: GITHUB_TOKEN: *** ARTIFACTS_SHA: e945cf6d4eb18ac65e4de8767ac85fc1ffffffff ARTIFACTS_DIR: artifacts/e945cf6d4eb18ac65e4de8767ac85fc1ffffffff `==> Repository: MyOrganization/MyProject` `==> Artifact name: ` `==> Local path: artifacts/e945cf6d4eb18ac65e4de8767ac85fc1ffffffff` `==> Workflow name: Build.yml` `==> Workflow conclusion: success` `==> Commit: e945cf6d4eb18ac65e4de8767ac85fc1ffffffff` Error: Not Found

Looking through the code, I don’t see any condition that my workflow might be encountering.

Lastly, thank you for an excellent GitHub action!

I was receiving same error and turned out that github token didnt had access to other repo. Check your token.

Another way to download artifacts is using the Gitub CLI tool “gh” - we just switched to using this as a step instead in a cross workflow use case:

        id: download
        run: |
          gh run download --name myproj-build-main --dir ${{env.working-directory}}/build
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

(We had a “Error: no artifacts found” failure case so different from this issue probably, but might apply to the comment talking about “action in a different workflow within the same repository”)

@erno thank you for the tip, that will probably help people in need of a workaround. I was able to do something similar using Python and the GitHub Artifacts API.

FYI, I think the error you are seeing “Error: no artifacts found” is a different symptom than the “Not Found” error, which as I indicated above is likely being returned by the HTTP response.
