Random errors on nightly

[skoch13]

While I'm not able to find exact pattern, but sometimes opening a buffer might result in a following:

  Error  19:14:52 msg_show.lua_error Error executing vim.schedule lua callback: ...al/share/nvim/lazy/auto-save.nvim/lua/auto-save/init.lua:76: Invalid buffer id: 381

That sounds like it tried to save a buffer that can't be saved. While there are some safeguards against it, it might be that we've missed something. Could you share your auto-save.nvim config?

Sure, here it is:

  {
    "okuuva/auto-save.nvim",
    cmd = "ASToggle",
    event = { "InsertLeave", "TextChanged" },
    opts = {
      execution_message = {
        enabled = false,
      },
      condition = function(buf)
        local fn = vim.fn
        local utils = require("auto-save.utils.data")

        if utils.not_in(fn.getbufvar(buf, "&filetype"), { "NeogitStatus" }) then
          return true
        end
        return false
      end,
      trigger_events = {
        immediate_save = { "FocusLost" },
        defer_save = { "CursorHold", "TextChanged", "InsertLeave" },
        cancel_defered_save = { "CursorMoved", "CursorHoldI" },
      },
      debounce_delay = 3000,
      write_all_buffers = true,
    },
  },

I think I just need to add more ft to ignore. Found two more for mini.files and neogit, will see how it goes.

This looks like the buffer that was going to be saved was either unloaded or invalid. So adding a check with nvim_buf_is_loaded({buffer}) at the beginning of the save function in init.lua would probably fix this.

I pushed a fix to this issue. Please check it out for yourself and see if it solves your problems.

@primeapple looks like it worked, thank you!
