typescript - Firebase cloud functions code ELIFECYCLE error

Question

When trying to deploy the initial code provided by firebase init for cloud functions by calling firebase deploy the following error occurs. The source code inside index.ts has not been modified as it is the case with the rest of the project.

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

Answer 1

add typeRoots to the tsconfig.json within the functions folder

{
  "compilerOptions": {
    "module": "commonjs",
    "noImplicitReturns": true,
    "noUnusedLocals": true,
    "outDir": "lib",
    "sourceMap": true,
    "strict": true,
    "target": "es2017",
    "typeRoots": [
      "./functions/node_modules/@types"
    ],
  },
  "compileOnSave": true,
  "include": [
