First question that needs to be asked, do you have the Sunset Invasion DLC activated.
Second, which event exactly are you consoling to try and spawn the invasion force?
I don't have the DLC, but looking through the event file it seems to be a long event chain. So simply skipping ahead by 4 or more events will of course cause problems. Certain flags won't be set, certain preperations won't be made and it sounds like the event you are triggering is desinged to fire for the Aztec Emperor himself, not for the person he is invading.
Try console triggering the very first event in the chain and go from there.
