Hello Nullnite,
I haven't actually tried creating my own summons yet but that was on my agenda, so I went ahead and did so tonight.
Pretty confident I know what's going on. You haven't assigned equipment to the summon, which is resulting in the errors, so fixing the one thing should resolve all your errors.
First, is the GUID of what you're summoning a Root Template that you copied and modified? I would recommend that above all else. Then you want to do a few things with the root template:
1) tag it as a summon. Whether that's a requirement, I'm not sure, but anything summoned has that tag so I'd do so. Just click on the tags and add SUMMON.
2) give it an equipment set. Choose something that sounds generic; in my example I have chosen Undead_Skeleton_Staff_Water to give my mage a water staff. It is my understanding & experience that this staff is automatically levelled appropriately. You can make your own equipment set in Stats>Equipment if desired. Since your summon is an NPC, remember not to worry about armor/etc.
3) give it a skillset, or give it individual skills you specify. Self-explanatory. Or you can create a skillset in stats.
4) assign it a (character) Stats set. Again, it's my understanding these stats alter automatically based on character level (as a summon, summon level matches summoner, so all good). Pick one you find appropriate.
5) since it is a summon, I would make sure Lootable is set to false. Also, Visual Set Indices at the top is where you choose appearance options for your summoned npc, if any. Make sure the root template ID you copy/create has the kind of appearance options you want.
Picture below for help. That should get you started well, though.
