Error in deploy Cloud Functions .json not found - json

Question

I can not deploy my functions when I try to import a .json credential file.
When running firebase init functions I selected the TypeScript
option.
Then I put my functions in TypeScript and tried loading the .json
file with the credentials of my project in order to use
firebase-admin.
/functions (Directory)
tsconfig.json

"lib": ["es6"],
"module": "commonjs",

"esModuleInterop": true,
"resolveJsonModule": true,
},
"compileOnSave": true,
"include": [
"src",
"./typings.d.ts"

typings.d.ts:
declare module "*.json" {
const value: any;
export default value;
}

-- serviceAccountKey.json
-- index.ts
index.ts:
import * as admin from 'firebase-admin';
import * as serviceAccount from './serviceAccountKey.json';
admin.initializeApp({
credential: admin.credential.cert(serviceAccount),
databaseURL: "DATABASE-URL"
});
If I remove the import works normally, I can not deploy when I import the file.

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

Answer 1

You should use require() (not import) to pull in the contents of a JSON file. If you really must use import (I don't recommend it), read this.

Answer 2

If I remove the import works normally, I can not deploy when I import the file.
A few tsconfig options are missing:
"esModuleInterop": true,
"resolveJsonModule": true,
