Error: Error parsing triggers: Cannot find module 'cors'
Require stack:

• /home/hc-06/Documents/ReactMLFireBaseApp-/MLReactapp/functions/index.js
• /home/hc-06/.nvm/versions/node/v12.2.0/lib/node_modules/firebase-tools/lib/triggerParser.js

Try running "npm install" in your functions directory before deploying.

@orlandomendozagarrido please follow the issue template. The required fields are required :)

This is most likely a bug in your code @orlandomendozagarrido (but it's impossible to tell without the rest of the issue template).

Your code definitely either has require("cors") or import * from "cors" and you don't have that module installed into your functions directory (and it's associated package.json).

Try running npm install cors in your functions/ directory.

Closing due to lack of author response.

Try to delete package-lock.json file and node_modules folder and run again npm install (while you are inside functions folder)
