Xandra Cassandra Connection Error

Hi guys, when I am trying to connect to a local Cassandra database running on using this configuration case Xandra.start_link(nodes: [“”], authentication: {Xandra.Autheniticator.Password, [username: username, password: password]}) do {:ok, conn} -> {:ok, conn} true -> IO.puts(“suck bubble”)
I’m getting this error:

`[error] GenServer #PID<0.7526.0> terminating
** (RuntimeError) Connect raised a UndefinedFunctionError error. The exception details are hidden, as
they may contain sensitive data such as database credentials.

(xandra) Elixir.Xandra.Protocol.erl:61: Xandra.Protocol.encode_request/3
(xandra) Elixir.Xandra.Connection.Utils.erl:75: Xandra.Connection.Utils.authenticate_connection/4
(xandra) Elixir.Xandra.Connection.erl:31: Xandra.Connection.connect/1

Last message: nil
State: Xandra.Connection
[error] GenServer IntelliJElixir.Debugger.Server terminating`

I put the app username and password which I defined in cqlsh.

Using GUI Cassandra client I am able to connect to DB without problems.

Any Ideas, I tried everything…
