[core-workspaceFolder] - Invalid folder: undefined, full path required.

[npearson72]

I'm seeing [core-workspaceFolder] - Invalid folder: undefined, full path required. in my coc-nvim.log.

I'm not sure where it's coming from. The only workspace settings I have in my coc-settings.json are:

"workspace.rootPatterns": ["package.json", ".gitignore", ".env", ".git"],

I want to say it's also related to this log:

[provider-manager] - Provider error on provideCodeActions: _ResponseError: Request workspace/configuratio      ↪n failed with message: Cannot read properties of null (reading 'length')

Which happens when I call: keyset("n", "<leader>as", "<Plug>(coc-codeaction-source)", opts)

Any ideas?

What's your :CocInfo?

This is my coc-settings file:

https://github.com/npearson72/dots/blob/master/ansible/roles/neovim/files/nvim/coc-settings.json

[fannheyward]

The error is came from

coc.nvim/src/core/workspaceFolder.ts

Line 32 in 1e46b27

logger.error(`Invalid folder: ${fsPath}, full path required.`)

The workspace folder value is null in this case. How to reproduce this? or any sample repo?

[npearson72]

@fannheyward thanks for responding.

I have created a sample repo for some other issue (completely unrelated to this one). The reason I'm offering to use it is because that sample repo uses a monorepo, and the problem I've described in this discussion can be observed in it: https://github.com/npearson72/example-biome-bug

Here again is the the error I am seeing when using :CocOpenLog:

2025-08-16T19:45:58.943 ERROR (pid:24305) [core-workspaceFolder] - Invalid folder: undefined, full path required.

My coc-settings.json can be located here: https://github.com/npearson72/dots/blob/master/ansible/roles/neovim/files/nvim/coc-settings.json

Also, my entire neovim init.lua configs (in case this helps): https://github.com/npearson72/dots/blob/master/ansible/roles/neovim/files/nvim/init.lua

And specifically the coc.nvim plugin: https://github.com/npearson72/dots/blob/master/ansible/roles/neovim/files/nvim/lua/plugins/coc.lua

NOTE: The error appears whenever I trigger telescope.nvim. My shortcut for that is ctrl+p. As I watch the logs, I can trigger telescope to appear, and immediately when I close it by hitting esc, the error appears.

Also, this will occur even if I have an empty coc-settings.json file and if I do not install any coc extensions.

Hope this helps?

If there is any more I can do, please let me know.

[fannheyward]

Thank you for your demo repo. Can you provide any steps? I cloned this repo, :e to edit the tsx files, didn't encounter the Invalid folder for now.

[npearson72]

Perhaps I can create a minimum coc.nvim config? Do you happen to have telescope.nvim installed? It seems that launching it triggers these issues in coc.nvim. Not sure why.

[fannheyward]

Also tested with telescope.nvim, my steps:

1. cd into the demo repo, nvim
2. :Telescope find_files, open the apps/example-app/src/main.tsx
3. gd on App to jump
4. :Telescope find_files, open the packages/example-package/src/lib/C.tsx
5. check :CocOpenLog, no Invalid folder

[npearson72]

That is very puzzling. Any chance you'd be open to trying my configs?
nvim.zip

I've tried disabling most of the features and still I continue getting that error.

[fannheyward]

Sorry I didn't test your config. Try minimal vimrc, only coc.nvim + telescope.nvim.
