Describe the problem/error/question
When using the Google Calendar Oath “Get Many” node in n8n, the workflow fails with an error stating:
“Cannot read properties of undefined (reading ‘dateTime’)”
It is weird because it is just one google calender which is not working the other three are working.
It seems that some events retrieved from Google Calendar do not contain a start.dateTime field, leading to a crash in the workflow.
What is the error message (if any)?
