Google Calendar Scheduler

Good afternoon,

I am setting up a system in the school openhab and I need to use gcal. I have already installed and configured it several times, including with 2 emails and I always end with the same error in the log:

[DEBUG] [io.gcal.internal.GCalEventDownloader] - gcal feed contains no events …

and in the calendar I have a simple event just to change a switch for testing, in the description “send Tomada_Sala ON”.

In google API management, requests are identified and without errors.

Where can my error be that more debugging can I do?

Thank you for your help.
