The error happens while trying navigate autocomplete menu with arrows. The configuration is the same of the example except the theme.

Sorry for the delay

OK this is interesting. I've never come accross this before because I don't use arrow keys for the completion menu, but I can reproduce it now.

The issue is that arrow keys have a different way of dealing with completions, see :help popupmenu-keys:

\ Select the next match, as if CTRL-N was used, but don't insert it.

So when preparing to fetch the signature help or documentation to populate a popup, the line looks like Console., whereas it looks like Console.Beep when using CTRL-N.

I'm not quite sure what the best thing to do is. I think we'll have to try to do something a bit hacky and modify the line in the server documentation request.

OK I think this should do it.

There's an edge case that this fix doesn't handle, and that is using a combination of CTRL-N/CTRL-P and arrow keys. That is, if you navigate the completion list with CTRL-N/CTRL-P and then with arrow keys, there will be empty documentation popups for the arrow key navigations. But there will not be any errors.
