Most likely node.photos is not initialized because the initialization happens in oauth2Client which is only called when the credentials are expired at the time we call oauth2Client.refreshAccessToken(which is called at start and every 45 minutes).

So if we keep some patience it might automatically resolve itselves when refreshing the toking after expiration.

[janvda]

When initalizing node.photos = new Photos(node.config.credentials.accessToken);
we know get following error:

I have same problem on macbook installation - so it looks like the google api is recently behaving differently so that tokens are no longer refreshed.

[janvda]

npm install --save-exact google-auth-library@5.6.1

[janvda]

it is working again on macbook although I didn't change anything.
macbook has the following configuration:
