I’ve set up a GitHub Actions workflow that triggers whenever a pull request is created into the develop branch. The purpose of this workflow is to automatically bump the npm version of my Angular project and create a corresponding tag. Although the workflow jobs are executing successfully, there’s an unexpected issue: when pushing the new tag (under the -name: Push Tag step), the develop branch is inadvertently getting deleted (refer to the attached image).

I have a general question too, Which branch, main or develop, is the optimal choice for bumping a version and creating a tag?

enter image description here

name: prettying, Semantic Versioning, and Tagging
on:
  pull_request:
    types: [opened, reopened, synchronize]
    branches:
      - develop

jobs:
  update-version:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout Repository
        uses: actions/checkout@v4
        with:
          fetch-depth: 0

      - name: Set Git User Identity
        run: |
          # Create 'secrets' variables in Repository secrets(repository -> settings -> Secrets and Variables -> Actions -> Repository secrets)
          git config --global user.email "${{ secrets.GIT_USER_EMAIL }}"
          git config --global user.name "${{ secrets.GIT_USER_NAME }}"

      - name: Setup Node.js
        uses: actions/setup-node@v4
        with:
          node-version: "20"

      - name: Pretty checking & auto formating
        run: |
          echo "executing prettier commands."
          npm ci
          npm run prettier:check
          npm run prettier:format

      - name: Determine Version Increment Level
        id: determine-version-level
        run: |
          # Check based on Conventional Commits.
          # The command git log --format=%B -n 1 retrieves the commit message of the latest commit (-n 1 specifies that we want the message of the most recent commit).
          commit_message=$(git log --format=%B -n 1)
          echo "commit_message...: $commit_message"
          if [[ $commit_message == *"breaking changes:"* || $commit_message == *"breaking change:"* || $commit_message == *"BREAKING CHANGE:"* ]]; then
            echo "version-level=major" >> $GITHUB_OUTPUT
          elif [[ $commit_message == *"feat:"* || $commit_message == *"feature:"* ]]; then
            echo "version-level=minor" >> $GITHUB_OUTPUT
          else
            echo "version-level=patch" >> $GITHUB_OUTPUT
          fi

      - name: Update Version Numbers using npm
        run: |
          version_level=${{ steps.determine-version-level.outputs.version-level }}
          echo "Version Level...: ${{ steps.determine-version-level.outputs.version-level }}"
          # Update version number and force increment
          npm version $version_level --force

      - name: Get Latest Tag & Save it
        id: get_tag
        run: echo "TAG=$(git describe --tags --abbrev=0)" >> $GITHUB_ENV

      - name: Create Tag
        run: git tag ${{ steps.get_tag.outputs.TAG }}

      - name: Push Tag
        run: git push origin ${{ steps.get_tag.outputs.TAG }}:develop

I have tried with different git tag commands but have not succeeded.

Note: I do not want to use any package/library from Marketplace.
