Check your log

firebase-debug.log

Answer 3

Wherever you're using the functions key word, you must also import the proper library:

Example:

exports.helloWorld = functions.https.onRequest((request, response) => {
  functions.logger.info("Hello logs!", {structuredData: true});
  response.send("Hello from Firebase!");
});

then import const functions = require("firebase-functions");
