[error] Error: An unexpected error has occurred.

Answer 1

You said that:

1. You have updated firebase-functions to version 1.0.2
2. The code is cloned from the Cloud Function sample without any change

So most probably your problem comes form the fact that Cloud Functions V1.0.0 and above have changed, see the doc https://firebase.google.com/docs/functions/beta-v1-diff#storage

You should change from

exports.generateThumbnail = functions.storage.object().onFinalize((object) => {

to

exports.generateThumbnail = functions.storage.object().onFinalize((object, context) => {

and adapt accordingly the lines based on object, following the doc.
