I'm having the same issue. Have you found a solution yet?

Here's what ChatGPT gave me. It works well enough now, for me. I will note that since I was switching back and forth between index.html and a file in a subdirectory, index.html could not find its CSS file. In this case, I had to open index.html first, and the other file as a tab, and everything is good so far.

Synchronize Vim's Working Directory

Ensure Vim's cwd is consistent across tabs. You can achieve this by automatically syncing the working directory with the current file's directory:

Add this to your init.lua file:

vim.api.nvim_create_autocmd("BufEnter", { pattern = "*", callback = function() vim.cmd("lcd " .. vim.fn.expand("%:p:h")) end, })

This ensures that the working directory always matches the directory of the currently active buffer.

The provided solution managed to work as a temporary workaround, as it thankfully prevented the 'ENOENT' error. However, it only functions between two adjacent buffers and fails to load changes from the third buffer. A more comprehensive and detailed solution is needed to fully address this issue.

I've successfully made the necessary adjustments to ensure it works as expected by tweaking the config file. Simply add the provided lines to your init.lua config file, and you'll have an improved version of the workaround. While I can't guarantee it's 100% flawless, it does work smoothly now and updates each buffer without any errors—unlike before. Please note, it will only function correctly if loaded automatically when opening the index.html file from the root working directory.
