Im following learn Next.js from their website and on chapter 6 in which I have to upload my project to github in order to deploy it on vercel. I receive this message "Warning: Could not identify Next.js version, ensure it is defined as a project dependency."
Error: No Next.js version could be detected in your project. Make sure "next" is installed in "dependencies" or "devDependencies" however I checked my package.json and install next.js again and still no change. If anyone knows how to solve this issue I would appreciate it thank you.

I linked my github repository so you can see my whole project and structure
