Requirements

[X] I have read and followed the instructions above and understand that my issue will be closed if I did not provide the required information.

Svelte Files are not registered automatically by formatting.prettier (as you can read here: https://github.com/nvimtools/none-ls.nvim/blob/main/doc/BUILTINS.md#notes-39)

So you would have to enable it like this:

null_ls.setup({
  sources = {
    formatting.prettier.with({ extra_filetypes = { "svelte" } }),
    formatting.stylua,
    diagnostics.eslint_d,
  },
  -- configure format on save
  on_attach = function(current_client, bufnr)
    if current_client.supports_method("textDocument/formatting") then
      vim.api.nvim_clear_autocmds({ group = augroup, buffer = bufnr })
      vim.api.nvim_create_autocmd("BufWritePre", {
        group = augroup,
        buffer = bufnr,
        callback = function()
          vim.lsp.buf.format({
            filter = function(client)
              -- only use null-ls for formatting instead of lsp server
              return client.name == "null-ls"
            end,
            bufnr = bufnr,
          })
        end,
      })
    end
  end,
})
