[BUG] No changes detected for new tag

[mpern]

Is there an existing issue for this?

• I have searched the existing issues

Does this issue exist in the latest version?

• I'm using the latest release

Describe the bug?

When trying to build a new release tag (v*), the action does not select any previous commit and fails to report any changes.

To Reproduce

1. create workflow triggered on tag push:

on:
  push:
    tags:
      - v*

2. add and commit some dummy files, over a few commits
3. tag the latest commit as v1.0.0 and push the tag

What OS are you seeing the problem on?

ubuntu-latest or ubuntu-22.04

Expected behavior?

Changes detected correctly.

Relevant log output

changed-files
  Using local .git directory
  Running on a push event...
  Warning: No previous tag found
  Error: Unable to locate the commit sha: 
  Error: Please verify that the commit sha is correct, and increase the 'fetch_depth' input if needed
  Retrieving changes between  () → e6eb9203c6c2c87b4dad7177f06eddb6ad80e024 (v1.0.0)
  All Done!

Has all relevant logs been included?

• I've included all relevant logs

Anything else?

I've enabled fetch-depth: 0 for my checkout step, so it's not like the history is missing.

Hi @mpern, can provided the full workflow code including the checkout and changed-files configuration note the fetch-depth needs to be set to 0 for the checkout action.

Example

on:
  push:
    tags:
      - 'v*'

jobs:
  release:
    name: Release
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v4
        with:
          fetch-depth: 0

      - name: Get changed files
        id: changed-files
        uses: tj-actions/changed-files@823fcebdb31bb35fdf2229d9f769b400309430d0 # v46

      - name: List changed files
        env:
          ALL_CHANGED_FILES: ${{ steps.changed-files.outputs.all_changed_files }}
        run: |
          echo "List all the files that have changed: $ALL_CHANGED_FILES"

      - name: Get changed files in the .github folder
        id: changed-files-specific
        uses: tj-actions/changed-files@823fcebdb31bb35fdf2229d9f769b400309430d0 # v46
        with:
          files: .github/**

      - name: Run step if any file(s) in the .github folder change
        if: steps.changed-files-specific.outputs.any_changed == 'true'
        env:
          ALL_CHANGED_FILES: ${{ steps.changed-files-specific.outputs.all_changed_files }}
        run: |
          echo "One or more files in the .github folder has changed."
          echo "List all the files that have changed: $ALL_CHANGED_FILES"
...
