Request initialize failed with message: Cannot read properties of undefined (reading 'dynamicRegistration')

[dustinlyons]

Hello,

I'm seeing the following error after verifying tailwindcss server is installed. The lsp server is unable to start. I'm running Emacs 29.0.50 in Daemon Mode on NixOS.

LSP :: Connected to [volar-api:5162/starting][volar-html:5163/starting][volar-doc:5164/starting][tailwindcss:5166/starting].
LSP :: Error from the Language Server: Request initialize failed with message: Cannot read properties of undefined (reading 'dynamicRegistration') (Internal Error)
LSP :: volar-api:5162 initialized successfully in folders: (/mnt/state/Projects/Code)
LSP :: volar-html:5163 initialized successfully in folders: (/mnt/state/Projects/Code)
LSP :: volar-doc:5164 initialized successfully in folders: (/mnt/state/Projects/Code)

Results of lsp-describe-session:

Here is my emacs configuration. I've tried a few things with same results.

1. Using the package from ELPA by excluding the line with :straight.
2. lsp-tailwindcss-add-on-mode turned off.

(use-package lsp-tailwindcss
  :straight (:type git :host github :repo "merrickluo/lsp-tailwindcss")
  :init
    (setq lsp-tailwindcss-add-on-mode t))

(use-package web-mode
  :hook (web-mode . lsp-deferred))

(add-to-list 'auto-mode-alist '("\\.jsx?$" . web-mode))
(add-to-list 'auto-mode-alist '("\\.vue\\'" . web-mode))

(defun web-mode-init-hook ()
  "Hooks for Web mode.  Adjust indent."
  (setq web-mode-markup-indent-offset 2))
(add-hook 'web-mode-hook  'web-mode-init-hook)

(straight-use-package
 '(lsp-volar :type git :host github :repo "jadestrong/lsp-volar"))

(use-package lsp-volar)

Hello @merrickluo and @dustinlyons, I have same problem too.

I'm running GNU Emacs 28.1 on macOS from Homebrew. I'm installed lsp-tailwindcss and (setq lsp-tailwindcss-add-on-mode t), the LSP server will run, but it will never finish loading indefinitely.

Please check.

[merrickluo]

Hi, can you please check your language server version with M-x lsp-tailwindcss-installed-server-version? the output from lsp-workspace-show-log would also be helpful.

[takueof]

@merrickluo Thanks for your reply.

Hi, can you please check your language server version with M-x lsp-tailwindcss-installed-server-version? the output from lsp-workspace-show-log would also be helpful.

OK, I tried.

M-x lsp-tailwindcss-installed-server-version

Sorry, that command doesn't show up in the minibuffer...

M-x lsp-workspace-show-log

It worked. But all I got was the following message in the minibuffer:

IO logging is disabled

Is there anything else I can do...?

• lsp-tailwindcss: 20220816.1602
• lsp-mode: 20220907.1628
• lsp-ui: 20220823.1626

[merrickluo]

i see, ~you need the package to be loaded before running lsp-tailwindcss-installed-server-version, this can be done by opening a file with lsp-tailwindcss enabled~. I probably should autoload it. just realized I didn't make this function interactive, please update and try again.

And about show log, I forgot to mention that you need to toggle it on first with lsp-toggle-trace-io. if you get an error with lsp-tailwindcss-installed-server-version, you should reinstall the server with C-u lsp-install-server and then select tailwindcss.

Thanks! I installed the latest version (20220910.347) and tried it.

M-x lsp-tailwindcss-installed-server-version

Return 0.8.5.

M-x lsp-workspace-show-log (after M-x lsp-toggle-trace-io)

I chose Workspace: tailwindcss:97266/starting (Timestamp: UTC+9):

[Trace - 02:06:12 PM] Sending notification 'textDocument/didClose'.
Params: {
  "textDocument": {
    "uri": "file:///Users/takueof/test.tsx"
  }
}

This is the only output. I hope this information helps you.

[merrickluo]

Thanks, @takueof, the server version seems good. For the log, can you try another time with the following steps?

1. turn on logs with lsp-toggle-trace-io
2. if the server is already started, use lsp-workspace-restart to restart it.

Since the problem is likely on server startup, this is the only way to see the startup logs. It will be great if you can get a minimal example that I can reproduce it, thanks :pray:

[takueof]

@merrickluo Oh, I see. I've attached the log where I tried the following steps:

1. Turn on lsp-toggle-trace-io
2. Restart with lsp-workspace-restart
3. Show logs by lsp-workspace-show-log

M-x lsp-workspace-show-log

Thank you @takueof. I see, the new version of lsp-mode removed a lot of options related to dynamicRegistration which cause tailwindcss server failed to start, I might need sometime to find out how to workaround this, meanwhile you can pin lsp-mode to an old version if you are able to, I can confirm that "3fa645c0397b8f438f2db2dd288b899ba330d410" works.

@merrickluo Thanks for confirming.

Oh...😭 I see. I hope you can work around this issue 🙏

meanwhile you can pin lsp-mode to an old version if you are able to, I can confirm that "3fa645c0397b8f438f2db2dd288b899ba330d410" works.

OK, I'll try to stick with this hash version of lsp-mode.

Best regards.

[merrickluo]

Correction: I misread the diff output, turns out it's lsp-mode is supporting dynamicRegistration now, but it triggered a bug in the language server that didn't check for nil before reading some of the capabilities. I'll send a PR there. https://github.com/tailwindlabs/tailwindcss-intellisense/pull/602

[takueof]

@merrickluo Thank you for creating PR, and congrats on the merge 🎉 The latest version of Tailwind CSS IntelliSense was just released and the latest version is 0.8.7.

I tried (setq lsp-tailwindcss-server-version "0.8.7"), M-x lsp-update-server (choose tailwindcss) and restart GNU Emacs.

I have confirmed that it works fine! 👍

As for the remaining work, do you just set defcustom's lsp-tailwindcss-server-version to "0.8.7"?

Best regards.

[merrickluo]

Yes, I did test locally too, and hten updated the custom variable, I think we can close this one now, cheers :beer:
