I'm having the same issue as many are facing by searching on the web https://issuetracker.google.com/issues/178403179. I have enabled domain-wide delegation for my service account. I can get events and I can add events without attendees. When added attendees, it throws this error
```
Error: Service accounts cannot invite attendees without Domain-Wide Delegation of Authority.
```
I searched the web and tried every suggestion I could find but it is still getting the same error. Please help.
I'm hoping to get this resolved soon. Can someone please help?
