`affected:build` failing in the pipeline

Current Behavior

The affected:build is failing with the message:

fatal: Not a valid object name master
fatal: No such ref: 'master'

Although, the git fetch is being called and branches are existing at the time the command is called

These worked for me

1. Add --base origin/master to nx affected:build
2. Fetch all the branches with GitHub action by setting fetch-depth: 0

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

[erdysson]

For the ones running into issue on Gitlab CI, two things to make it work;

First; set the git depth via UI to 0, under settings -> CI CD -> General pipelines -> git depth And second, add GIT_FETCH_EXTRA_FLAGS: --unshallow in .gitlab-ci.yml under variables

EDIT: GIT_FETCH_EXTRA_FLAGS: --unshallow worked only in the first run, for following runs runner throws error:

fatal: --unshallow on a complete repository does not make sense

The solution I found is setting the depth as 0, and passing --base=origin/master to affected command
