How to use the environment variables in the deployed GitHub pages using Next.js?

[poxii]

To prevent using .env file, I added .env file on .gitignore.
And I added the environment variables on GitHub environment variables for github-pages.
However the environment variables were not loaded in the action file as below.

      - name: Build Next.js
        env:
          BASE_PATH: ${{ secrets.BASE_PATH }}

The environment variable BASE_PATH always contains empty.
How to fix it?

Hello, @poxii
It seems to use the secret variables on the GitHub page environment.
It can work if you use the repository's secret variables instead of the GitHub page environment's secret variables.
I hope it helps your work.
Thank you.
