No `bibfile`. Did you instantiate `bib = CitationBibliography(bibfile)` and pass `bib` to `makedocs` as an element of the `plugins` keyword argument?

Unable to determine the repository root URL for the navbar link. This can happen when a string is passed to the `repo` keyword of `makedocs`. To remove this warning, either pass a Remotes.Remote object to `repo` to completely specify the remote repository, or explicitly set the remote URL by setting `repolink` via `makedocs(format = HTML(repolink = "..."), ...)`.
