## TL;DR

[ChiragAgg5k (maintainer)]: This was a server bug, fixed in Appwrite 1.9.0 (PR #11413): create-user endpoints typed name as non-nullable string, so passing name: null threw a vague server error. If you hit it, upgrade to 1.9.0 or newer, or just omit the name field entirely as a workaround.
