Can't change the preview branch in Vue.js with Github Pages

I’m trying to get my project deployed, but I got an error when gh-pages commit to update Github Pages website after a commit from github-actions:

sh: line 1: vue-cli-service: command not found
Error: Command "vue-cli-service build" exited with 127

I can’t change the preview branch which is gh-pages

Current versus Expected behavior

Expected behavior:
Successfully deployed the website from Vercel

Current behavior:

Error message saying:

sh: line 1: vue-cli-service: command not found
Error: Command "vue-cli-service build" exited with 127

Code, configuration, and steps that reproduce this issue

Added vue-cli-service in package.json in master branch.

Hey @lulunac27a. I’m not sure I follow what you’re doing with GitHub Pages and Vercel. Can you walk me through your workflow step by step?
