Stuck with node for reading out Google calendar

General
1

I have created a nice workflow for an interactive family calendar with Neopixels. In 2018 I have used node-red-node-google. After several updates, the authentication with Google does not work any more.
When using the callback authentication with the URL http://node-red.example.com:1880/google-credentials/auth/callback (which is resolved in hosts-Files correctly) the following error message is shown:

Now I am looking for a solution to get the calendar node back to work.
Has anybody a complete how-to use a calendar node and to do proper authentication?

looked further into this...

I made a new Google Project, added Calendar API. I clicked 'credentials' in the left menu, added OAuth client where I added http://localhost:1880/google-credentials/auth/callback in the Authorised redirect URIs.
Use the client ID and secret in a new node red google and you're all settled
