Question posted in 
I have a problem with start my NextJS project.
When I started on my computer with using command "npm run dev" everything it works correctly.
I have a problem in the moment when I can use for example Vercel or when I clone git repository on another computer on school. I don’t know what the problem is, but maybe in enviroment who is cannot been on github repository because he is written in gitignore or something what i have in gitignore makes this problem.
This is my github repository. https://github.com/ThomasTomanec/portfolio-website

This is my github repository when i have this problem. https://github.com/ThomasTomanec/portfolio-website
Yes, it is because of the environment variable. You have to add this variable in the computer, which builds the project – if you build the project with GitHub Actions, you have to provide the environment variable there. If it is somewhere else, I am pretty sure there is a way to add the environment variable.
