functions predeploy error: Command terminated with non-zero exit code2

[Vijay1126]

Hey everyone, I just started with the first tutorial "Getting Started with Cloud Functions for Firebase using TypeScript - Firecasts" on YouTube.
While trying to deploy the code, I get the error shown below.

Device: Macbook Pro
Node version: v12.16.3
Typescript version: version 3.8.3

Expected behavior

Deploy successfully

Actual behavior

vijayraja@Vijays-MBP functions % firebase deploy

=== Deploying to 'pleasework-770e8'...

i  deploying functions
Running command: npm --prefix "$RESOURCE_DIR" run lint

> functions@ lint /Users/vijayraja/newfire/functions
> tslint --project tsconfig.json

Running command: npm --prefix "$RESOURCE_DIR" run build

> functions@ build /Users/vijayraja/newfire/functions
> tsc

Error: functions predeploy error: Command terminated with non-zero exit code2

I have attached the all the screenshots below:

Error:

My index.ts file :

Firebase.json file:

tsconfig.json file:

package.json file:

I'm aware there are other threads with the same issue, but I tried all of them, none of them worked.
What I tried doing:

1. Place the "typeRoots" key inside "compilerOptions" (Functions only deploy erroring, referencing parent application node_modules folder firebase-tools#749)
2. npm run build and restart VSCode (Functions only deploy erroring, referencing parent application node_modules folder firebase-tools#749)

Please help.

@Vijay1126 did you save your index.ts file before trying to deploy? That's a linter error that's saying the functions variable defined in line 1 of index.ts isn't used. You use it in line 6, so I think it's just a matter of saving that file and trying again 😄
