Answer 1

If you just want to finish a tutorial, just change Node version from 10 to 8 in package.json

"engines": {
  "node": "8"
}

This will now work, but eventually after February 15, 2021 deployment of Node.js 8 functions will no longer be allowed. So, if you want to use cloud functions after this date you must be on Blaze pay-as-you-go billing plan.
