Error in symlink: Cannot write outside of the repository directory

[hbf17517]

I am using bazel 8.1.1 My MODULE.bazel contains the following:

bazel_dep(name = "rules_android_ndk", version = "0.1.3")
android_ndk_repository_extension = use_extension("@rules_android_ndk//:extension.bzl", "android_ndk_repository_extension")
use_repo(android_ndk_repository_extension, "androidndk")  

When I build I get the following error:

INFO: Repository rules_android_ndk++android_ndk_repository_extension+androidndk instantiated at:
  <builtin>: in <toplevel>
Repository rule android_ndk_repository defined at:
  C:/users/rob/_bazel_rob/q6nhqnyq/external/rules_android_ndk+/rules.bzl:127:41: in <toplevel>

I discovered that p and repo_relative_path are of the same value: C:/Users/rob/AppData/Local/Android/Sdk/ndk/28.0.13004108/toolchains/llvm/prebuilt/windows-x86_64/AndroidVersion.txt It looks like string.replace at https://github.com/bazelbuild/rules_android_ndk/blob/main/rules.bzl#L112 doesn't work!

    for p in ctx.path(ndk_path + clang_directory).readdir():
        repo_relative_path = str(p).replace(ndk_path, "")
+        print("p=",p,"repo_relative_path=",repo_relative_path)
        # Skip sysroot directory, since it gets its own BUILD file
        if repo_relative_path != sysroot_directory:
            ctx.symlink(p, repo_relative_path)

Any idea what's happening? Thank you

The solution for me was the following:

diff --git a/rules.bzl b/rules.bzl
