When run, it throws an error saying the following:

400: {"errcode":"M_UNRECOGNIZED","error":"Unrecognized request"}
Check your server details are correct.

The server details are definitely correct, because I can use curl with the same information and get a response from the server, like so:

 deadvcr@lambda-core:~$ curl -XPOST -d '{"type":"m.login.password", "user":"{username}", "password":"{password}"}' "https://matrix.org/_matrix/client/r0/login"
{
    "access_token": "{access token}",
    "device_id": "{device id}",
    "home_server": "matrix.org",
    "user_id": "@{username}:matrix.org"
}

For the SERVER variable, you should simply use the top level domain and protocol, not the full path to the login endpoint.

In your case, it should probably read SERVER = "https://matrix.org"

Ah, that makes sense. Thank you for the help, keep up the great work!
