How can I cancel a GitHub Actions workflow if the commit has no tag - github

Question

I have npm publish github actions, I want to run this action if my commit has tag, otherwise I don't want to run my action because of that if I do not add any tag my commit then action is run and failed because it try to publish already publish npm package with same tag. For example with my last commit I have tag 1.2.3 and my npm package was publish with 1.2.3 version. When I add new commit to my branch without any tag actions try to publish my package with 1.2.3 version tag so it failed. Here my actions code below, is there any solution for it.
Thanks for advive.

push:
branches:

EDITTED VERSION
I edit my yml file base on #Enrico Campidoglio suggestion but still is does not work. I made two commit first one without tag and it canceled the action but second one has tag it still canceled action. Is there any new suggestion or solution ?

I found the solution finally after too many tried. I changed my mind and try to run shell script and it works :)
Just add that line in my yml file
- name: Check Git Tag to continue publish
run: ./scripts/publish.sh
and I created a sh file for control the commit tag. You can find the latest script and yml file definitions below
Here is my lastest yml file, npm-publish.yml
name: NPM Publish
on:
push:
branches:
- master
jobs:
build:
name: Build 🏗 & Publish 🚀
runs-on: ubuntu-latest
steps:
- uses: actions/checkout#v1
- uses: actions/setup-node#v2.4.0
with:
node-version: 12
registry-url: https://registry.npmjs.org/
- name: Check Git Tag to continue publish
run: ./scripts/publish.sh
- run: npm install
- run: npm publish --access public
env:
NODE_AUTH_TOKEN: ${{secrets.NPM_TOKEN}}
Here is my script file, publish.sh
#!/usr/bin/env bash
GIT_COMMIT=$(git rev-parse --short HEAD)
GIT_TAG=$(git describe --tags --exact-match $COMMIT || :)
if [[ ${GIT_TAG} == v* ]] ; then
echo "$GIT_TAG Tag found..."
else
echo "No git tag found, action cancelled..."
exit 1
fi

For the time being, there isn't an official action to cancel the current workflow. There is, however, an official GitHub API and a third-party action that invokes it. You could combine it with an if conditional and the github context to achieve what you want:
steps:
- uses: andymckay/cancel-action#0.2
if: startsWith(github.ref, 'refs/tags')
Be aware that cancelling a workflow through the API is an asynchronous operation, which means that later steps might still get executed until the workflow runner handles the request.
A much more solid approach would be to put a condition on your publishing step to only run when the workflow was triggered by a new tag:
steps:
- run: npm publish --access public
if: startsWith(github.ref, 'refs/tags')
env:
NODE_AUTH_TOKEN: ${{secrets.NPM_TOKEN}}
