When using the profession skill tier endpoint, the category names for ‘Weapon Enchants’ are returned incorrectly. Instead of returning as ‘Weapon Enchantments’ as they appear to on the api documentation (and as all other categories do), they return as ‘Weapon Echantments’.
I have only noticed this on the Shadowlands Weapon Enchantments.
Profession Skill Tier
In addition. Enchantment profession skills do not include the produced item_id for their sellable enchants.
