Cross-posted from [this Github issue](https://github.com/non-Jedi/lsp-julia/issues/50).

I set up `lsp-julia` in emacs to automatically initialize the `LanguageServer` once I navigate to a Julia file. However, when I try to type the letter `d` anywhere in the body of the file, I obtain an error (reproduced below) in `julia-ls::stderr`.

Is there a way to disable the relevant functionality in `get_func_hover` or `collect_completions` so that I can use `lsp-julia` without it constantly crashing? `company-dabbrev` is sufficient for my purposes, so I do not need completions from `lsp`.
