Nvim_lsp - schema problems for jsonls server

Language Server Protocol (LSP)
1

Hello!

I’m trying to add a schema for jsonls, but when I do this my configuration doesn’t work like expected.

My LSP configuration is the following:

local status_ok, nvim_lsp = pcall(require, "lspconfig")
if not status_ok then
	return
end


local function lsp_keymaps(bufnr)
	local function buf_set_keymap(...) vim.api.nvim_buf_set_keymap(bufnr, ...) end
	local opts = { noremap=true, silent=true }
	
	buf_set_keymap('n', 'gD', '<cmd>lua vim.lsp.buf.declaration()<CR>', opts)
	buf_set_keymap('n', 'gd', '<cmd>lua vim.lsp.buf.definition()<CR>', opts)
	buf_set_keymap('n', 'K', '<cmd>lua vim.lsp.buf.hover()<CR>', opts)
	buf_set_keymap('n', 'gi', '<cmd>lua vim.lsp.buf.implementation()<CR>', opts)
	buf_set_keymap('n', '<C-k>', '<cmd>lua vim.lsp.buf.signature_help()<CR>', opts)
	buf_set_keymap('n', '<space>wa', '<cmd>lua vim.lsp.buf.add_workspace_folder()<CR>', opts)
	buf_set_keymap('n', '<space>wr', '<cmd>lua vim.lsp.buf.remove_workspace_folder()<CR>', opts)
	buf_set_keymap('n', '<space>wl', '<cmd>lua print(vim.inspect(vim.lsp.buf.list_workspace_folders()))<CR>', opts)
	buf_set_keymap('n', '<space>D', '<cmd>lua vim.lsp.buf.type_definition()<CR>', opts)
	buf_set_keymap('n', '<space>rn', '<cmd>lua vim.lsp.buf.rename()<CR>', opts)
	buf_set_keymap('n', '<space>ca', '<cmd>lua vim.lsp.buf.code_action()<CR>', opts)
	buf_set_keymap('n', 'gr', '<cmd>lua vim.lsp.buf.references()<CR>', opts)
	buf_set_keymap('n', '<space>e', '<cmd>lua vim.diagnostic.open_float()<CR>', opts)
	buf_set_keymap('n', '[d', '<cmd>lua vim.lsp.diagnostic.goto_prev()<CR>', opts)
	buf_set_keymap('n', ']d', '<cmd>lua vim.lsp.diagnostic.goto_next()<CR>', opts)
	buf_set_keymap('n', '<space>q', '<cmd>lua vim.diagnostic.setloclist()<CR>', opts)
	buf_set_keymap('n', '<space>f', '<cmd>lua vim.lsp.buf.formatting()<CR>', opts)
end

local on_attach = function(client, bufnr)
	lsp_keymaps(bufnr)
end

local capabilities = vim.lsp.protocol.make_client_capabilities()
capabilities = require('cmp_nvim_lsp').update_capabilities(capabilities)

local signs = {
  { name = "DiagnosticSignError", text = "" },
  { name = "DiagnosticSignWarn", text = "" },
  { name = "DiagnosticSignHint", text = "" },
  { name = "DiagnosticSignInfo", text = "" },
}

for _, sign in ipairs(signs) do
  vim.fn.sign_define(sign.name, { texthl = sign.name, text = sign.text, numhl = "" })
end

local config = {
  -- disable virtual text (virtual text is the text that appears near an error)
  virtual_text = false,
  -- show signs
  signs = {
    active = signs,
  },
  update_in_insert = true,
  underline = true,
  severity_sort = true,
  float = {
    focusable = false,
    style = "minimal",
    border = "rounded",
    source = "always",
    header = "",
    prefix = "",
  },
}

vim.diagnostic.config(config)

local servers = { 'tsserver','jsonls' }
for _, server in ipairs(servers) do
  local opts = {
		on_attach = on_attach,
		capabilities = capabilities,
	}

  nvim_lsp[server].setup(opts)
end

and with this I have the following output
Capture

Now, if I this code before nvim_lsp[server].setup(opts)

  if server == "jsonls" then
    opts = {
      on_attach = on_attach,
      capabilities = capabilities,
      settings = {
        json = {
          schemas = {
            {
              description = "NPM configuration file",
              fileMatch = {
                "package.json",
              },
              url = "https://json.schemastore.org/package.json",
            },
          }
        }
      }
    }
  end

but the LSP diagnostics doesn’t show me any error if I press <space>e or <space>q and the icons from the left are no longer present either.
If I do :LspInfo I can see the client listed, but errors are no longer displayed.

I’m doing something wrong?

Here is how it looks when I add the schema.
