I am working on a project that I downloaded, but having trouble setting up and getting the enviroment started. After yarn install, yarn build, and then yarn start-https, I get this error message:

I am have followed the set for the readMe file... and I tried googling each line of error message but nothing had helped solved this issue of exiting out.

I feel, that I must be missing something... somthing that was not documented in the readme file...

Any help would be greatly appreciated.
