Just wanted to put this here since the 17w47b snapshot sheds a little more light on what's going on:
Essentially, it's a direct result of the .DS_store bug (MC-121380), giving the error:
Non [a-z0-9/._-] character in path of location: <namespace>:loot_tables/.DS_Store
Not sure why it gives the false error, even though '.DS_Store' technically only has [a-z0-9/._-] characters...

As far as I can tell, the bug also affects the new 17w46a snapshot.
Digging through the output logs a bit more, I can see where the .ds_store file bug comes into play. Thanks again @tryashtar !
Sorry about that. I've attached a zipped version of the datapack I'm using. Note that I'm using the unzipped version in order to get the error.
Also, I've attached the error from the output log, in case that helps.
Thank you both for looking at this!
This is a fairly old issue (updated as of 1.9, I think). It was updated in favor of two new tags:
HandItems:[{},{}] (Two for dual-wielding)
ArmorItems:[{},{},{},{}] (For the four armor slots)
Try this for the zombie:
/summon Zombie ~ ~ ~ {HandItems:[{id:stone_sword,Count:1b},{}],ArmorItems:[{},{},{},{}]}
Ah, I see. Thank you for clearing that up!
