functions/lib/functions/src/index.ts does not exist, can't deploy Cloud Functions

When I try deploying my Firebase cloud functions I get the following error.

Desired behavior: Deploy functions successfully.

Error:

Error: There was an error reading functions/package.json:

functions/lib/index.js does not exist, can't deploy Cloud Functions

Solved:

I was able to solve the problem by removing everything associated with Firebase functions. And running: firebase init again. After I cd functions run npm install. Then I was able to deploy successfully after fixing an error with:
