- Tue Nov 29, 2016 7:46 pm #58866 Hey guys,
I'm getting an Exception(3) error in serial when running a GetNextEventChoreo from Temboo to retrieve a Google Calendar event. I've spent hours looking but can't find someone with a similar issue. I've nailed the issue down to the GetNextEventChoreo.read(); command but don't know why it produces the error. Perhaps something to do with running out of memory?
I can run other scripts fine, such as the create event choreo (except for the part where it runs GetNextEventChoreo.read() to output the event it created).
