attempt to index field 'title' (a number value)

[Kohirus]

I use mason.nvim to install LSP servers, DAP servers, linters, and formatters. After I started Neovim, then I type :Mason command to open Mason's window, When the installed server package check update was complete, I received the following error message:

Error executing vim.schedule lua callback: ...k/packer/start/nvim-notify/lua/notify/render/default.Lua:9:attempt to index field 'title'(a number value)

This is likely a bad notification being called with a number title. I've added a validation check so you'll get a strack trace with the location of where it's called now

I took a look and your dotfiles define a global error function. This overrides the builtin in error function which is used by a lot of code. Don't do this. In general avoid defining globals unless they have very specific names that are not going to be used by anything else

Now the plugin works properly！Thank you！I will close the issue.
