just attempted this and i got the following error?

TypeError: Cannot read properties of null (reading 'getEvents') (anonymous) @ Code.gs:19

Suggestions?

Did you change const id = "[email protected]"; to use the email address from the source account?

Yes, I did change it to the email to the source account.
