Error when triggering <Ctrl-X><Ctrl-O> completion

[mhanberg]

Describe the bug

When i hit control-x-o to trigger some completions (from LSP), I get a nvim-cmp popup that has no text in it and an error. The completions are still in the popup if i move through them with ctrl-n or ctrl-p, but you can't read what they say.
