tabby complete returns error

[marvinlnnx]

I have tried two different model of tabby and I have installed tabby-mode on my doom-emacs, and also I have added the url to the url but it returns error:

error in process filter: Symbol's value as variable is void: callback

I used these 2 models:

~ ❯❯❯ tabby serve --device metal --model StarCoder-7B

by the way I have copied the tabby.el content to custom.el and updated the url and restarted my emacs

(require 'json)
(require 'subr-x)
(require 'url)
(require 'url-http)

(eval-when-compile
  (defvar url-http-end-of-headers))

(defgroup tabby nil
  "Minor mode for the Tabby AI coding assistant."
  :link '(url-link "htps://tabby.tabbyml.com")
  :group 'programming)

(defcustom tabby-api-url "http://127.0.0.1:8080"
  "URL to Tabby API."
