On Firebase deploy in VSCode, multiple errors in node_modules/firebase-functions/lib/common/params.d.ts

Question

Basically what the title says. I'm trying to deploy cloud functions to Firebase using Typescript and I get 25 errors in node_modules/firebase-functions/lib/common/params.d.ts

I have not touched this file and I have no idea what it is. I have deployed many times in the past with no issue, so I'm assuming this must be due to some kind of update.

The only reference to this issue I have found so far is here: https://github.com/firebase/firebase-tools/issues/5138

This is exactly my problem, but I have updated Typescript and the issue persists. Can anyone suggest something else to try?

In case it helps, here are the error messages:

Try running npm outdated to make sure that you don't have an outdated package.

I had a similar issue with those versions :

Package                  Current   Wanted  Latest  Location                              Depended by
tslint                    5.20.1   5.20.1   6.1.3  node_modules/tslint                   functions
typescript                3.9.10   3.9.10   4.9.4  node_modules/typescript               functions

Upgrading them to their latest had solved it for me.
