Code actions not working in neovim

Describe the bug In neovim, code actions work when choosing one of the “correction” option, but not when choosing one of the following:

• Add <word> to dictionary
• Hide false positives
• Disable rule

Steps to reproduce Steps to reproduce the behavior:

1. Create a markdown file with the following line CustomWord is not a word
2. CustomWord is rightly marked as not a correct word
3. Move the cursor on it
4. Type: :lua vim.lsp.buf.code_action()
5. Choose 5: Add 'CustomWord' to dictionary
6. Nothing happens, the error is still here. And there is no error message either.

Expected behavior I expect it to add the CustomWord to dictionary and remove errors linked to it in the rest of the document, without having to manually add the word in the configuration.

Sample document

CustomWord is not a word

LTeX configuration I’m using it in neovim with lspconfig and nvim-lsp-installer with the default config, just calling it:

nvim_lsp.ltex.setup {
  on_attach = on_attach
  }

LTeX LS log No error log unfortunately.

Based on the work-around @David-Else provided in the comment above, I added a local dictionary capability. The VS Code extension version creates ltex.dictionary.en-US.txt file under .vscode/ directory and adds the word to this text file, by default, when add-to-dictionary option is selected in VS Code. Based on this behavior, I come up with the following solution. The code snippet vim.fn.expand("%:p:h") gets the absolute path of the Neovim buffer, so the provided solution looks for a .vscode/ltex.dictionary.en-US.txt hierarchy in the same directory. Then, the lines in both global user dictionary and local dictionary are utilized if these paths are valid. You can change/add different paths as well. One of the caveats is that the provided solution is not dynamic as in the VS Code extension, i.e., if you update the dictionary .txt file, you need to restart Neovim. This problem can be prevented by defining an autocmd to revaluate the table of words.

local paths = {
    vim.fn.stdpath("config") .. "/spell/ltex.dictionary.en-US.txt",
    vim.fn.expand("%:p:h") .. "/.vscode/ltex.dictionary.en-US.txt",
}

local words = {}
for _, path in ipairs(paths) do
    local f = io.open(path)
    if f then
        for word in f:lines() do
	    table.insert(words, word)
	end
	f:close()
    end
end

lspconfig.ltex.setup {
  on_attach = on_attach,
  settings = {
    ltex = {
      dictionary = {
        ['en-US'] = words,
        ['en-GB'] = words,
      },
    },
  },
}

I use this workaround, you can add words to your normal Neovim spelling directory and ltex-ls will use them. Not perfect, but works!

-- add vim user dictionary for ltex-ls
local path = vim.fn.stdpath 'config' .. '/spell/en.utf-8.add'
local words = {}

for word in io.open(path, 'r'):lines() do
  table.insert(words, word)
end

lspconfig.ltex.setup {
  on_attach = on_attach,
  settings = {
    ltex = {
      dictionary = {
        ['en-US'] = words,
        ['en-GB'] = words,
      },
    },
  },
}
