<simpleError: Cannot install packages: .... values must be length 1, but FUN(X[[1]]) result is length 0>

As initially reported here, solve() fails when the Remotes section of the package DESCRIPTION includes a url such as url::https://gitlab.miracum.org/miracum/misc/dizutils/-/archive/development/dizutils-development.zip.

A reproducible example:

repo_path <- file.path(tempdir(), "reproduce-issue")
git2r::clone(
  url = "https://github.com/miracum/dqa-dqastats",
  local_path = repo_path
)
