Omnicompletion for the new native lsp completion

[entropitor]

When I set up neovim using https://neovim.io/doc/user/lsp.html#vim.lsp.omnifunc(), this plugin fails with the following error

Vim(return):E117: Unknown function: v:lua.vim.lsp.omnifunc

How can I fix this?

[yami-beta]

asyncomplete-omni.vim is omni completion source of asyncomplete.vim. Maybe, neovim's native lsp completion does not use asyncomplete-omni.vim.

[entropitor]

@yami-beta they use omni function but they use a lua function to do so. This is configured using v:lua:... and that seems to be erroring in this plugin

I guess it's related to this

After struggling, this worked for me:

I really not familiar with VimScript so please anyone improve this!!
