Fail to deploy to Github Pages - Blazor webassembly using GitHub Actions

Question

I think I have followed all the steps to deploy Blazor webassembly on GitHub Pages using GitHub Actions which I found from https://www.davideguida.com/how-to-deploy-blazor-webassembly-on-github-pages-using-github-actions/

But it failed at Deploy to Github Pages step

• Set up job (Passed)
• Run actions/checkout@v2 (Passed)
• Setup .NET Core (Passed)
• Publish with dotnet (Passed)
• Deploy to Github Pages (Failed)
• Post Run actions/checkout@v2 (Passed)
• Complete job (Passed)

Here are the error descriptions

You need to create a branch named development from master branch and set development branch as default branch in your repository settings.

This is because your gh-pages.yml files has BASE_BRANCH: development and BRANCH: master

with:
    ACCESS_TOKEN: ${{ secrets.ACCESS_TOKEN }}
    BASE_BRANCH: development # The branch the action should deploy from.
    BRANCH: master # The branch the action should deploy to.
    FOLDER: build/wwwroot # The folder the action should deploy.
    SINGLE_COMMIT: true

so that deployment will happen from development branch to master branch
