Alright so to fix this problem, all you wanna do is switch the version of actions/checkout from v1 to v2 and remove the fetch-depth option

# ...
jobs:
  build:
    steps:
      - uses: actions/checkout@v2 # from v1 and no with: fetch-depth: 0
# ...

And to try and explain to you the problem, originally in v1 of the actions/checkout, the action was making a complete clone of the repo (or an unshallow clone) but later on in v2, the team at github decided to make the action perform shallow clones instead (and that’s what started this issue in the first place). So to try and circumvent this, I decided to add the

git fetch --prune --unshallow

command as built into this action’s (heroku-deploy) code. But now the action only works on shallow clones 😅 (since the action makes them unshallow anyway). I did this because I suspected most people would use v2 of the actions/checkout action and wouldn’t think to add the fetch-depth: 0 flag so by having unshallowing built into the heroku-deploy action, they wouldn’t even need to think about it. But its pretty clear now I’ll need to work on a more elegant situation which I will do in the next release.

FOR THE TIMEBEING THOUGH, FOR ANY FUTURE USERS RUNNING INTO THIS ISSUE, make sure that you are using v2 of the actions/checkout action and you have not set the fetch-depth: 0 flag exactly as given in the documentation. I’m gonna try adding the shallow and unshallowing issues in the docs as well (atleast until I can find a way to circumvent it)

P.S @balexandre sorry for the late reply, I suspect we live in different timezones and I was asleep when you commented

Actually I think I found the problem, in the official docs for the actions/checkout@v1 github action, it says

fetch deep

The second line says that by default, the action only fetches one commit. That could be the reason why the clone is coming off as a shallow one. To fix this, try adding the following line in your main.yml inside your .github/workflows folder:-

name: Deploy

on:
  push:
    branches:
      - master

jobs:
  build:
    runs-on: ubuntu-latest
      steps:
        - uses: actions/checkout@v1
          with:             # ADD THIS LINE
            fetch-depth: 0  # ADD THIS LINE
        - uses: akhileshns/heroku-deploy@master
          with:
            heroku_api_key: ${{secrets.HEROKU_API_KEY}}
            heroku_app_name: "YOUR APP's NAME (must be unique to heroku)"
            heroku_email: "YOUR EMAIL"
            buildpack: "SOME BUILDPACK [OPTIONAL]"

And hopefully that fixes it
