Firebase Functions Node JS: Cannot find module './auth/credential' - node.js

Question

After updating to the latest dependencies my Firebase Functions backend won't run in either firebase emulators:start or firebase functions:shell. It fails with the following exception

I have tried
Update everything to the latest dependencies (using ncu -u)
Assured that admin.initializeApp() is called
index.ts
import * as admin from 'firebase-admin'
admin.initializeApp()
[...]
I've also tried to initialize the app explicitly
index.ts
import { ServiceAccount, initializeApp, credential } from 'firebase-admin'
import * as serviceAccount from './api-key.json'
initializeApp({
credential: credential.cert(<ServiceAccount>{
projectId: serviceAccount.project_id,
clientEmail: serviceAccount.client_email,
privateKey: serviceAccount.private_key
})
})
[...]
Both give the same error. I need to test my code before deploying it to the backend.
Any help or hint is appreciated. Thanks
Edit: Now I get a new error:
