Next.js Deployment Assistance Required

I'm having trouble deploying my Next.js application. It works perfectly on localhost, but I'm encountering file path issues when trying to deploy it on my domain folder. I need a professional to help me solve these issues. Additionally, I will need explanations and the modified or added versions of any of the JSON files!

Ideal skills for this project include:
- Proficiency in Next.js
- Expertise in file path configurations
- Experience with JSON file modifications
- Ability to provide clear explanations

Please bid only if you can assist me with this problem and help me understand the changes made. Thank you.
