Hello Ben,
Looks like this example was not updated. ClientCustomerId is a required
field now.
You can resolve the issue by changing line
graph = adwords.use_mcc() {managed_customer_srv.get(selector)}
to
graph = managed_customer_srv.get(selector)
Also, would you mind logging a bug on the tracker regarding this issue?
