External dependency of buildfarm fails with bzlmod

[werkt]

A simple example of a new bazel workspace which uses a bzlmod dependency on buildfarm fails to build:

MODULE.bazel:

bazel_dep(name = "build_buildfarm")
local_path_override(
    module_name = "build_buildfarm",
    path = "/path/to/buildfarm",
)

command:
bazel build @build_buildfarm//src/main/java/build/buildfarm:all

Results in a number of different errors, depending upon the action executed:
