UnhandledPromiseRejection with the reason: ufo/provider/lsp.lua:61: service not started

[romgrk]

Neovim version (nvim -v | head -n1)

NVIM v0.7.2

Operating system/version

archlinux

How to reproduce the issue

Install Coc & setup ufo with:

local ufo = require('ufo')

ufo.setup({
  open_fold_hl_timeout = 0,
})

vim.keymap.set('n', 'zr', ufo.openAllFolds)
vim.keymap.set('n', 'zm', ufo.closeAllFolds)

Then do some work, and at some point the following message keeps appearing at every 5 seconds (triggered by many actions, such as write file, or cursor movement):

Error executing vim.schedule lua callback: UnhandledPromiseRejection with the reason:                                                                                                                                
...vim/site/pack/packer/start/nvim-ufo/lua/ufo/provider.lua:51: ...site/pack/packer/start/nvim-ufo/lua/ufo/provider/lsp.lua:61: service not started 
...re/nvim/site/pack/packer/start/nvim-ufo/lua/ufo/fold.lua:89: in function <Anonymous:70>

No ufo.log found.

Expected behavior

Actual behavior

Look like your coc.nvim issue. Run UfoDisable to verify whether or not.

Yeah, sometimes it's stopped. It would be nice if ufo could handle that state more gracefully.

Fixed, ignore service not started error message directly.
