Cannot register bot client

[LecrisUT]

I have tried using the documented method of registering the bot client with ./bin/mbc auth --register, but I get the following error:

10:57:56ERRORserverError in handler
10:57:56ERRORserverTraceback (most recent call last):

mautrix.errors.request.MUnrecognized: Unrecognized request

I've tried accessing the url manually at _matrix/client/r0/register and _matrix/client/r0/admin/register I get the same Unrecognized request. Sorry I can't debug further as I'm unfamiliar with how to interface with APIs. At least I believe the former does not work because I've disabled user registration, and I can't find any documentation of the latter to check if I can manually invoke it.

I see this problem is related to #88 and other issues.

The mbc auth didn't work for me either. I think in my case the issue was that my reverse proxy forwards everything with /_matrix/* to synapse but mbc auth runs against /_matrix/maubot. This will also break if you change the base url of maubot.

Anyway, I worked my way around by using curl.

curl -X POST --header 'Content-Type: application/json' -d '{
    "identifier": { "type": "m.id.user", "user": "USERNAME" },
    "password": "PASSWORD",
    "type": "m.login.password"
}' 'https://MATRIXHOSTNAME/_matrix/client/r0/login'

Replace USERNAME, PASSWORD and MATRIXHOSTNAME according to your configuration. The server should reply with a .json containing the access token.

For me, the reverse-proxy is set correct, i.e. I can access both the matrix server and maubot manager. Login seems to be accessible, but the registration is not.

Using curl POST on _matrix/client/r0/register I get a session and some other JSON output, while _matrix/client/r0/admin/register gives the usual Unrecognized request.
I've tried editing with and without admin in the url, but both give Unrecognized request and I don't see directly where the registration_shared_secret is included in the payload.

maubot/maubot/management/api/client_auth.py

Lines 91 to 103 in 7688083

	res = await api.request(Method.GET, Path.admin.register)
	nonce = res["nonce"]
	mac = generate_mac(secret, nonce, username, password, user_type=user_type)
	try:
	return web.json_response(await api.request(Method.POST, Path.admin.register, content={
	"nonce": nonce,
	"username": username,
	"password": password,
	"admin": False,
	"mac": mac,
	# Older versions of synapse will ignore this field if it is None
	"user_type": user_type,
	}))

Edit: looking more into that python file, it looks like it first need to GET a response from which to generate the POST, however if I try to GET at the same URL, there's only Unrecognized request

Not _matrix/client/r0/register but _matrix/client/r0/login. It'll reply with a couple of variables including "access_token", which is what you need.

Ok so alternatively, I can manually create the users, log them in and get the access_token. Problem is I am using OAuth to login, and I don't see an option to add a password while logged in in order to interface like that.
