# Troubleshooting

If you are using `cmp-nvim-lsp` with `cmp-nvim-tags`, you may face a weird error

`method workspace/symbol is not supported by any of the servers registered for the current buffer`.

This is because neovim will register `tagfunc` as `vim.lsp.tagfunc` when lsp is attached, and there's no attached lsps

supports `workspace/symbol` method. To prevent this behavior, add the following code in your config file:

Besides, `vim.lsp.tagfunc` may also have performance issue since it is calling

the lsp `workspace/symbol` method firstly and fallback to the default when the

former one returns no result.

If you feel that use `cmp-nvim-tags` is laggy, then you can consider to set `tagfunc` to nil.

```lua

on_attach = function(bufnr, client)

    vim.bo.tagfunc = nil

end

-- sqls is an example lsp that does not support workspace/symbol

-- change sqls to the lsp where the error happens

require('lspconfig').sqls.setup {

    on_attach = on_attach

}

-- Occasionally, due to potential execution order issues: you might set tagfunc

-- to nil, but the LSP could re-register it later. So that you may need a

-- "brute force way" to ask neovim will always fallback to the default tag

-- search method immediately.

TAGFUNC_ALWAYS_EMPTY = function()

    return vim.NIL

end

-- if tagfunc is already registered, nvim lsp will not try to set tagfunc as vim.lsp.tagfunc.

vim.o.tagfunc = "v:lua.TAGFUNC_ALWAYS_EMPTY"

```
