[Bug]: Sync All Tasks Google Calendar OAuth Integration fails

[Lorite]

Bug Description

I have connected Task Notes with Google Calendar using OAuth. The events are loaded correctly and I can see them in the calendar view. When I click on "Sync All Tasks", some tasks are synced incorrectly (around 60% out of 350 tasks).

I think the plugin is making 600+ requests in less than a minute which is over the maximum quota allowed. The issue is probably with the recurrent tasks without an end date.

Some logs:
