Vercel deployment issues (config, json)

Hi, i have got a next.js blog with a build error on Vercel (want to use Strapi as a CSM) I have been trying to fix the error and reinstalled node, yarn, npm …i also changed commas and strings (and code)…I have Lubuntu installed on my Computer(Mac)…anyway this is the Github repository. Any help is appreciated.

Error log:

Build error occurred
FatalError: tsconfig.json(45,7): error TS1005: ‘:’ expected.
