iCal Provider rejects request resulting in deletion of all calendar events

[babyarms]

It's not stated by the provider, but if they receive too many requests, they deny us from pulling from the iCal. The times are inconsistent, they can work within 5-minute sync times, or 1 hour sync times can cause an issue result in HTTP error 429. Is there a way to adjust the code to do a try/catch or completely quit upon URL response equaling to 429 to prevent deletion?

Currently, if we receive the HTTP 429 error, all events existing in the calendar are deleted. The next time it syncs, it creates new events, but becomes an endless loop. I was going through some other issues and someone else had a similar problem but didn't seem to be a solution. I'm only using one calendar and one iCal if that is relevant.

You can stop the execution and prevent removal of the events by adding

if (responses.length == 0)
      return;

above code.gs L160
