Error when calling gptel : (wrong-type-argument gptel-backend nil)

[Jedyle]

Hello,

I'm experiencing an issue than occurs only from the version that adds multi-llm support (https://github.com/karthink/gptel/commit/6419e8f021ef46d9657cbd9bdf631e33378eedeb). Previous versions work for me.

When calling gptel, I get the following error : (wrong-type-argument gptel-backend nil)

Here's my init.el setup

(straight-use-package 'gptel)

(defun read-gptkey-file ()
  "Read the content of `.gptkey' file in `~/.emacs.d/'."
  (with-temp-buffer
    (insert-file-contents (expand-file-name ".gptkey" (concat user-emacs-directory)))
    (buffer-string)))
(setq gptel-api-key (read-gptkey-file))
(setq gptel-model "gpt-3.5-turbo")

Here the error trace :

Debugger entered--Lisp error: (wrong-type-argument gptel-backend nil)

  funcall-interactively(execute-extended-command nil "gptel" "gptel")
  call-interactively(execute-extended-command nil nil)
  command-execute(execute-extended-command)```

My emacs version is 27.1.

Thanks by advance

It looks like something went wrong during the upgrade. Could you try the following?

1. Delete and reinstall gptel (instead of upgrading)
2. If that doesn't work, could you try manually loading gptel.el and gptel-openai.el? One way to do this would be with M-x load-library gptel and M-x load-library gptel-openai.
