won't work with code actions that will open up a new floating window

nvim -v

Run :checkhealth for more info

To be specific, null-ls.nvim + gitsigns.nvim wouldn't work for code action preview hunk minimal config

 require('packer').startup(function()
    use 'nvim-telescope/telescope.nvim'
    use 'nvim-telescope/telescope-ui-select.nvim'
    use 'lewis6991/gitsigns.nvim'
    use 'jose-elias-alvarez/null-ls.nvim'
end
)

require 'telescope'.setup {}
require('telescope').load_extension 'ui-select'
vim.keymap.set('n', 'gca', vim.lsp.buf.code_action, {})

require 'null-ls'.setup {
    sources = {
        null_ls.builtins.code_actions.gitsigns,
    }
}

Then open any file that has any unstaged changes, put cursor at the place where changes make, type gca, and select preview hunk, and it will show nothing.

However, if comment out this line, using default ui of code_action(), then preview_hunk works just fine

-- require('telescope').load_extension 'ui-select'

same issue, but it's sporadic.

Similar issue but with efm-langserver when vim.lsp.buf.formatting is called.

I think i found the cause of the problem from dressing.nvim. You can take my fork or try dressing.nvim which also provides the same select(telescope).
