After updating neovim to 0.81 and all plugins to latest release, autocmd to highlight words on cursor hold is not working on certain languages - neovim

Question

I have an auto command highlight words on cursor hold and this autocmd gets attached to buffer when the LSP server has the capability of documentFormattingProvider.
After updating neovim to 0.81 and all the plugins and language servers. The behaviour of this autocmd is buggy.
on svelte files, it does not work and actually outputs error: method textDocument/documentHighlight is not supported by any of the servers registered for the current buffer (lsp:svelte)
on python, no highlighting, no errors, but running lua vim.lsp.buf.document_highlight() on cmd line while cursor on repetitive word, it does highlight (lsp:pyright,black)
on go, it is working! (lsp:gopls)
on typescript files, it is working (lsp:tsserver)
on dart it is working (lsp:dartls)
Here is my dotfiles
local function lsp_highlight_document(client)
-- Set autocommands conditional on server_capabilities
if client.server_capabilities.documentFormattingProvider then
vim.api.nvim_exec(
[[
augroup lsp_document_highlight
autocmd! * <buffer>
autocmd CursorHold <buffer> lua vim.lsp.buf.document_highlight()
autocmd CursorMoved <buffer> lua vim.lsp.buf.clear_references()
augroup END
]],
false
)
end
end
I also tried (also not working):
local function lsp_highlight_document(client)
-- Set autocommands conditional on server_capabilities
if client.server_capabilities.documentFormattingProvider then
vim.api.nvim_create_augroup("lsp_document_highlight", { clear = true })
vim.api.nvim_clear_autocmds({ buffer = bufnr, group = "lsp_document_highlight" })
vim.api.nvim_create_autocmd("CursorHold", {
callback = vim.lsp.buf.document_highlight,
buffer = bufnr,
group = "lsp_document_highlight",
desc = "Document Highlight",
})
vim.api.nvim_create_autocmd("CursorMoved", {
callback = vim.lsp.buf.clear_references,
buffer = bufnr,
group = "lsp_document_highlight",
desc = "Clear All the References",
})
end
end
Both of these functions gets called here
options.on_attach = function(client, bufnr)
if client.name == "tsserver" then
client.server_capabilities.documentFormattingProvider = true
end
if client.name == "sumneko_lua" then
client.server_capabilities.documentFormattingProvider = false
end
lsp_highlight_document(client)
lsp_keymaps(bufnr)
end
local capabilities = vim.lsp.protocol.make_client_capabilities()
local status_ok, cmp_nvim_lsp = pcall(require, "cmp_nvim_lsp")
if not status_ok then
return
end
options.capabilities = cmp_nvim_lsp.default_capabilities(capabilities)
return options
Prior to this update, it was working fine in every language. Not sure what is missing.

Here is my config, which works for pyright, pylsp, lua-language-server etc.:
local api = vim.api
local lsp = vim.lsp
if client.server_capabilities.documentHighlightProvider then
vim.cmd([[
hi! link LspReferenceRead Visual
hi! link LspReferenceText Visual
hi! link LspReferenceWrite Visual
]])
local gid = api.nvim_create_augroup("lsp_document_highlight", { clear = true })
api.nvim_create_autocmd("CursorHold" , {
group = gid,
buffer = bufnr,
callback = function ()
lsp.buf.document_highlight()
end
})
api.nvim_create_autocmd("CursorMoved" , {
group = gid,
buffer = bufnr,
callback = function ()
lsp.buf.clear_references()
end
})
end
Works well on nvim 0.8.1. Try it to see if it works. If it does not work, I think there is something wrong with your config, you need to dig deeper to find why.
