Steps to reproduce

1. Follow the default config for the plugin
2. Add default tsserver config:

function _G.my_on_attach(client, bufnr)
    local opts = { noremap = true, silent = true }

    require("workspace-diagnostics").populate_workspace_diagnostics(client, bufnr) -- add behavior here
end

local getLspCapabities = function()
    local my_capabilities = require('cmp_nvim_lsp').default_capabilities()

    my_capabilities.textDocument.foldingRange = {
        dynamicRegistration = false,
        lineFoldingOnly = true
    }
    return my_capabilities
end

local my_capabilities = getLspCapabities()

local lspconfig = require('lspconfig')

lspconfig.tsserver.setup({ on_attach = _G.my_on_attach, capabilities = my_capabilities })

4. Error. It shows the messages and ignore any default config for the LSP server. For tsserver for example, it forgets to add tsconfig.json .

Expected behavior

No error.

Environment

• Neovim version: Nightly (NVIM v0.10.0-dev-2581+gd5488633f)
• workspace-diagnostics version: lastest
• Plugin clash: lspconfig + tsserver (also occurs with some others LSPs)

Closing since its a bug on nvim-highlight-colors that causes a missbehaviour on this plugin.
