hi there, so the error is clearly found here:

1:51:14 PM: npm ERR! syscall open

There is no package.json in your project for some reason. Maybe you forgot to commit it, or it is excluded via a .gitignore? We need a package.json file in order to install the correct versions of the dependencies your project needs in order to be built, and to determine which build scripts to run.

This general debugging post might also be helpful:
