Random error from :LspSaga hover_doc

[mikehaertl]

Describe the bug

I randomly get this error from LspSaga:

For context, my ShowHelp() just calls :LspSaga hover_doc:

" Show documentation for word under cursor using builtin :help for vim and
" help files and LSP for everything else
function! ShowHelp()
    if index(['vim','help'], &filetype) >= 0
        execute 'vert bo h '.expand('<cword>')
    else
        execute 'Lspsaga hover_doc'
    endif
endfunction

Steps to reproduce

I have no clear recipe to reproduce the issue.
