[bug] Random exception updating extmark

[Ajaymamtora]

Can the buffer id be checked before updating?

Error executing vim.schedule lua callback: ...are/nvim/lazy/nvim-lightbulb/lua/nvim-lightbulb/init.lua:170: scoped variable: Invalid buffer id: 218

I have a similar issue. Not sure why. But I'm getting the same stack dump. For anyone who cares, I posted a fix to my fork of the repo.

UPDATE: after making a couple of updates, I don’t have the problem anymore. I think what I have working in my fork of the repo provides a fix.
