GitHub Actions: `git push` to CodeCommit fails after rebase

I am currently working on a GitHub Action that saves my repository to AWS CodeCommit. It looks like this:

name: CI

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest
    
    steps:
      - name: "checkout"
        uses: actions/checkout@v2
      
      - name: "add aws codecommit remote"
        run: ...

      - name: "push repository to aws codecommit"
        run: |
          git fetch --tags
          git fetch --all
          git push aws --force --all
          git push aws --tags

This action works well, but you can break it by doing the following:

Checkout feature/a
Commit and push something
Checkout feature/b (from feature/a)
Commit and push something
Checkout master
Commit and push some things
Checkout feature/b
Rebase to master
Push again

Now I get the following error:

error: remote unpack failed: Unknown commit XXXX
To https://git-codecommit.my-region-1.amazonaws.com/v1/repos/***
 ! [remote rejected] feature/b -> feature/b (unpacker error)
error: failed to push some refs to 'https://git-codecommit.my-region-1.amazonaws.com/v1/repos/***'
Error: Process completed with exit code 1.

Funnily, it works if I perform the exact same steps on my local machine. I have checked many possible solutions to these problems, but they all suggest a force push or permission problems, which just isn't the case. I tried these solutions anyway, but nothing worked.

Does anyone have a tip for me?

Cheers and thank you in advance!

Solution

When using the action/checkout, you need to add the fetch-depth:0 variable if you wish to fetch all history: reference.

    steps:
      - name: "checkout"
        uses: actions/checkout@v2
          with:
           fetch-depth: 0
