Changes not detected on a manual trigger (workflow_dispatch)

[TuuZzee]

First of thanks for this action it's pretty neat!

I am using it on couple of my Github action workflow but I have one that can be trigger manually on any branch that doesn't seem to work as expected.
For some reasons the changes aren't detected, I am guessing I have configure this wrong but I am not sure where.
It's also giving me the warning: 'before' field is missing in event payload - changes will be detected from last commit
I have tried couple solution from other issues I found here but without success so far:

• Warning when workflow is triggered manually #158
• Support workflow_dispatch event #52

I have currently it set as such:

//...
on:
  workflow_dispatch:
//...

  checks:
//...
      - uses: dorny/paths-filter@v3
        id: filter
        with:
          base: ${{ github.ref }}
          filters: |

same issue here @dorny, the log show "changes will be detected from last commit" but every file is detected as a change.

Same for me. It seems the ref can't be found so all the commits are included for the change detection.

Hello,

I came here because I was facing the same issue. However, the solution suggested in #158 helped me solve it; absence of changes is now properly acknowledged on manual triggering.

Edit: My bad, the problem is still there. The solution above might have only worked out of luck.

This breaks all of our workflows that can also be run manually.

@dorny Looks like a bug with PR #53?

I was having the same problem described in the OP and this workaround worked for me!
