"No warnings can be incurred under -Werror" when enabling deps option B

While chasing another weird dependency issue, I followed the docs and enabled option B of the dependencies by setting the following flags on the tool chain:

   dependency_mode = "plus-one",
  strict_deps_mode = "error",
  unused_dependency_checker_mode = "error",
  dependency_tracking_method = "ast",

Now I have another weird error due to the "-Werror" flag set on this exact tool chain:

scalac failed: error executing command bazel-out/host/bin/external/io_bazel_rules_scala/src/java/io/bazel/rulesscala/scalac/scalac ... (remaining 1 argument skipped)

rules_scala version:

git_repository(
    name = "io_bazel_rules_scala",
    commit = "cd556ccfc253bfd70659631079e39be412b5402d",
    remote = "[email protected]:bazelbuild/rules_scala.git",
    shallow_since = "1649312900 +0300",
)

What can I do to keep using the -Werror flag?
