The depth of the AdUnit in the inventory hierarchy is greater
than is allowed. The maximum allowed depth is two below the effective
root ad unit for Ad Manager 360 accounts and is one level below the
effective root ad unit for Ad Manager accounts.
INVALID_PARENT
The only valid AdUnit.parentId for an Ad Manager account is the
Network.effectiveRootAdUnitId, Ad Manager 360 accounts can specify an ad unit
hierarchy with more than two levels.
UNKNOWN
The value returned if the actual value is not exposed by the requested API version.
