Help with deployment of a Next.js project on Vercel

Job ID: 37822284

Budget: £10 – £20 GBP

I am in need of an experienced developer with proficiency in Next.js and Vercel to help me deploy a project that I am having issues with.

The project runs fine locally, but when I deploy to vercel, I get the same issue each time...

I have spent hours trying to get this to work, and have been looking through various support pages, but it seems as though whatever I try, I cannot get rid of this error in vercel.

I'm looking for someone who can fork my repo, and then deploy the project themselves successfully on vercel, but most importantly to then explain to me what the problem was, as I am learning Next.js at the moment so want to understand how to fix these issues if they appear in future.
