@zerolfx Sorry to tag, but is it something obvious? thanks

[LazerJesus]

https://github.com/zerolfx/copilot.el/issues/185 https://github.com/zerolfx/copilot.el/issues/187 seems like a common issue atm. suggested solution is manual install and require. will try and feed back.

[LazerJesus]

  (add-to-list 'load-path  "emcas/straight/repo/copilot.el")
  (require 'copilot)

solves the issue for me, where copilot.el is the name of the folder containing the .el with the same name.

@LazerJesus I am still getting the following error

For a moment, it shows copilot agent started and then below stacktrace shows up

cc @emil-vdw @rakotomandimby Thankyou

[rakotomandimby]

@anildigital , noted. But at this point, I dont see how to solve.

[LazerJesus]

@anildigital i would love to help, but no clue 🦐

[anildigital]

@LazerJesus Can you paste the result of M-x emacs-version? Thanks

Mine is GNU Emacs 30.0.50 (build 1, aarch64-apple-darwin23.1.0, NS appkit-2487.20 Version 14.1.1 (Build 23B81)) of 2023-11-28 installed with brew emacs-plus@30

[LazerJesus]

GNU Emacs 30.0.50 (build 1, aarch64-apple-darwin22.6.0, NS appkit-2299.70 Version 13.5.1 (Build 22G90)) of 2023-11-29 installed with brew. emacs-plus@30

[anildigital]

@LazerJesus Thanks! Could you also share your emacs config to load copilot.el please. May be that would help to find out the difference and close the issue?

[jnavila]

My laptop at work which is stuck with emacs 28 is still performing correctly, whereas my home laptop (GNU Emacs 30.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.38, cairo version 1.18.0) of 2023-11-28) is having the same issue.

[jnavila]

I think I have found a cause of the issue. I'm using straight for package management, and copilot pulled jsonrpc in its dependencies. But it seems that jsonrpc is now part of core emacs, and the repo in the straight directory seems to have been stuck with an old version.

I just remove the jsonrpc repo and voilà!

[anildigital]

@jnavila I was not using the straight package though. I am still having the issue.

@rakotomandimby Not sure it's yet resolved.

[rakotomandimby]

@anildigital , please confirm that jsonrpc is not installed on your Emacs

[anildigital]

@rakotomandimby I don't see any jsonrpc package in elpa or in my emacs config? How one finds out if it's installed in Emacs? Thanks

[kliph-gladly]

@rakotomandimby I don't see any jsonrpc package in elpa or in my emacs config? How one finds out if it's installed in Emacs? Thanks

Hi all 😄 I believe you can check this by executing M-x describe-function and providing jsonrpc-error . That should take you to a *Help* buffer showing the jsonrpc-error function description. You should be able to view the source file for the function. In my case, this jsonrpc.el file lives in the "built-in" lisp directory of my Emacs installation.

[anildigital]

HI @kliph-gladly, there is no function defined jsonrpc-error in my Emacs. :|

[jnavila]

@anildigital OK, it may not be loaded by default it you don't have a dependency on it. M-x load-library then jsonrpc then describe the variable.

[anildigital]

@jnavila I couldn't see jsonprc-error in Ch-v

but I could see jsonrpc-connection it says

jsonrpc-connection’s value is ‘jsonrpc-connection’

This variable is obsolete since 25.1; use 'jsonrpc-connection instead

Base class representing a JSONRPC connection.
The following initargs are accepted:

:NAME (mandatory), a string naming the connection

:REQUEST-DISPATCHER (optional), a function of three
arguments (CONN METHOD PARAMS) for handling JSONRPC requests.
CONN is a ‘jsonrpc-connection’ object, method is a symbol, and
PARAMS is a plist representing a JSON object.  The function is
expected to return a JSONRPC result, a plist of (:result
RESULT) or signal an error of type ‘jsonrpc-error’.

:NOTIFICATION-DISPATCHER (optional), a function of three
arguments (CONN METHOD PARAMS) for handling JSONRPC
notifications.  CONN, METHOD and PARAMS are the same as in
:REQUEST-DISPATCHER.

[back]

Then I could see jsonrpc-error as a link, I clicked and it shows

jsonrpc-error is a native-compiled Lisp function in ‘jsonrpc.el’.

(jsonrpc-error &rest ARGS)

Error out with FORMAT and ARGS.
If invoked inside a dispatcher function, this function is suitable
for replying to the remote endpoint with an error message.

ARGS can be of the form (FORMAT-STRING . MOREARGS) for replying
with a -32603 error code and a message formed by formatting
FORMAT-STRING with MOREARGS.

Alternatively ARGS can be plist representing a JSONRPC error
object, using the keywords ‘:code’, ‘:message’ and ‘:data’.

[back]

I couldn't see any file path mentioned above.

[anildigital]

I clicked jsonrpc.el and it opened file with this path

/opt/homebrew/Cellar/emacs-plus@30/30.0.50/share/emacs/30.0.50/lisp/jsonrpc.el

So I am still getting the error even with in-build jsonrpc.el

[yubrshen]

Here is the debug trace triggered with --debug-init in emacs 29.1 with Doom, when I open a python file which started copilot-mode:

The function reporting the error is jsonrpc-request It is defined in ~/doom-emacs/.local/straight/repos/jsonrpc/jsonrpc.el ~/doom-emacs is my doom-emacs code. Based on the above fact, I suspect that it is a problem of incompatibility between the jsonrpc.el and the copilot.el

Here is my doom/info: https://pastebin.com/H43YQt5s

[anildigital]

Somehow copilot.el started working fine after I uninstalled Emacs and installed again Steps followed

brew uninstall emacs-plus@30
brew install emacs-plus@30 --with-native-comp

M-x emacs-version GNU Emacs 30.0.50 (build 1, aarch64-apple-darwin23.1.0, NS appkit-2487.20 Version 14.1.1 (Build 23B81)) of 2023-12-07

But sometimes when I run M-x copilot-diagnose, it keeps showing below error I did see File mode specification error: (jsonrpc-error request id=1 failed: (jsonrpc-error-code . -1) (jsonrpc-error-message . Server died) (jsonrpc-error-data))

along with Copilot agent started. multiple times, but failing.

For now it's working most of the times. May be this issue can be closed if others also don't see it.

[yubrshen]

I still have the same problem, even with re-installing doom code. I further tried with a minimal straight.el configuration, with nothing but copilot.el and its dependencies of jsonrpc.el The error is still the same:

Copilot agent started.
[jsonrpc] Server exited with status 2
jsonrpc-request: jsonrpc-error: "request id=1 failed:

It seems whenever copilot--request is called, which in terms calls jsonrpc-request, it will fail. Is there any change in copilot.el recently, for example, timeout value for connection request?

Here is my minimal setup to reproduce the problem, with emacs29.1 built in Ubuntu 22.4:

;; Boostrap code for straigt.el
(defvar bootstrap-version)
(let ((bootstrap-file
       (expand-file-name "straight/repos/straight.el/bootstrap.el" user-emacs-directory))
      (bootstrap-version 5))
  (unless (file-exists-p bootstrap-file)
    (with-current-buffer
        (url-retrieve-synchronously
         "https://raw.githubusercontent.com/raxod502/straight.el/develop/install.el"
         'silent 'inhibit-cookies)
      (goto-char (point-max))
      (eval-print-last-sexp)))
  (load bootstrap-file nil 'nomessage))
;; end of boostrap code for straight.el

;; Install a package from a Git repo:
(use-package copilot
  :straight (:host github :repo "zerolfx/copilot.el" :files ("dist" "*.el"))
  :ensure t)
;; you can utilize :map :hook and :config to customize copilot

The version of copilot is the latest :straight (:host github :repo "zerolfx/copilot.el" :files ("dist" "*.el")) It requires jsonrpc 1.0.14 the version pulled by straight.el of jsonrpc is 1.0.18 (I'm not sure if the difference matters.) Anything information you need? Unless my build emacs29.1 is problematic, there is not much else to suspect now.

[zerolfx]

@yubrshen Please try running node agent.js in your terminal. You can find agent.js in the dist folder.

[yubrshen]

@zerolfx Thanks for your pointer. I think that my problem has been solved! It turned that the node version had been forced to be v16.13.1. Running node agent.js thus failed. Once I switch node version to v18.19.0 (npm v10.2.3) Now, in my minimal configuration, M-x copilot-mode works now, I can even see code suggestion now.

Before I remember that the integration with neovim would require node v16.13.1. Sounds like that there is no more such constraint, but node agent.js would require node version 18.x.

[yubrshen]

By the way, for emacs29.1, it has bulit-in jsonrpc (1.0.16), but straight.el would pull with copilot.el a copy of jsonrpc (1.0.18). It seems it doesn't matter.

[zerolfx]

@yubrshen Glad to hear that your issue has been resolved. Yes, the upstream has updated the NodeJS version requirement, and I'll adjust this plugin to match.

[yubrshen]

Running node dist/agent.js might be added to a section of trouble-shooting or verification. It seems that it has to run successfully in order for copilot.el to work. It will help to resolve issues related to node, and JavaScript.

[peoplemerge]

I'm also seeing this error on Spacemacs a Pop!_OS 22.04 LTS using Node v20.10.0

node agent.js
Content-Length: 232

{"jsonrpc":"2.0","method":"LogMessage","params":{"level":0,"message":"[DEBUG] [agent] [2023-12-12T23:47:50.417Z] Agent service starting","metadataStr":"[DEBUG] [agent] [2023-12-12T23:47:50.417Z]","extra":["Agent service starting"]}}

This is unsurprising, since I can see in the following in Messages.

Copilot agent started.
