I've been playing around with the API a bit, and the documentation states the the hash of local gcodes files is in an MD5 format. It's not, it's a SHA1 hash. It's a super minor thing, but can bit confusing when your hashes don't match for some odd reason.
PRs are more than welcome to correct it - and the best place to report this if it's a proper doc error is the GitHub issues, things will get lost quickly here.
Or of course, you can edit it yourself & bypass the open an issue part.
