The /nbti tocommand command generates JSON that is invalid and will not work in command blocks.
The Numerical tags in lists (enchants, lore, attribute modifiers) are not supposed to be there
0: 1: 2: etc.
Numbers should not have the data type specified after the number (s, L, b, etc.); found in enchants, UUIDs, and the like.

It should be fixed now, please report any other problems. Thanks.
