SOLVED

Seems to be problem of the firebase-functions version,
for me worked:

Step1 - Update package.json versions from:
"firebase-admin": "5.1.0",
"firebase-functions": "^0.5.7"
to:
"firebase-admin": "^5.4.2",
"firebase-functions": "^0.7.1",

Step2 - Remove node_modules folder

Step3 - Run npm install
