conventional-changelog-action: Question: Why could it not detect the next version number?

I use the action to generate the next version number but since the main branch is protected, I (am trying to) dry run it using the following steps and create a new branch where it updates the version number using the npm version command. However, it says, “The version could not be detected, using fallback version ‘0.1.0’.”. What am I doing wrong?

- name: Checkout
  uses: actions/checkout@v3
  with:
    fetch-depth: 0
    ref: "main"

- name: Get the next version
  id: next_version
  uses: TriPSs/conventional-changelog-action@v3
  with:
    github-token: ${{ secrets.github_token }}
    skip-commit: 'true'
    skip-tag: 'true'

This is the run log:
