Error executing vim.schedule lua callback: /usr/share/nvim/runtime/lua/vim/lsp/util.lua:1600: 'height' key must be a positive Integer

I am seeing this error intermittently:

Error executing vim.schedule lua callback: /usr/share/nvim/runtime/lua/vim/lsp/util.lua:1600: 'height' key must be a positive Integer
stack traceback:
        [C]: in function 'nvim_open_win'

The (temporary) fix is to restart neovim.

branch master
commit 62cadce

Neovim v0.11.1

Thanks for submitting the issue. It seems to be caused by the calculation of the floating windows.
Could you provide more info reguarding the LSP you using and the function signature so it can be reproduced?

Thanks. I’m using lsp dart.

Here is a screenshot of it happening, with the cursor at the end of br.certifiedPlatforms.contains(pla

Even if I press enter a few times to get it to clear, the error keeps occurring until I restart neovim. Here’s a screenshot of it working immediately after restarting:

I wonder if it has something to do with my config. It shows the signature window at the top of the screen if the cursor is in the bottom half, and vice-versa. This works fine most of the time, and I am not sure what I might be doing differently to make this error manifest.

My lazyvim config:

return {
  'ray-x/lsp_signature.nvim',
  init = function()
    vim.cmd [[ hi LspSignatureActiveParameter guifg=#ffffff guibg=#0000ff ]]
    vim.api.nvim_create_autocmd('LspAttach', {
      callback = function(args)
        local bufnr = args.buf
        require('lsp_signature').on_attach({
          floating_window_off_y = function()
            local ratio = vim.fn.winline() / vim.fn.winheight(0)
            return ratio < 0.5 and 99 or -99
          end,
          hint_enable = false,
          max_height = math.floor(vim.fn.winheight(0) / 3),
          transparency = 10,
        }, bufnr)
      end,
    })
  end,
}

I am seeing this error even with the floating_window_off_y override removed from my config. I will now try running it with the max_height override also removed.
