Steps to Reproduce
You can clone this repository https://github.com/ggrossetie/testcontainers-node-windows and run the GitHub Actions.
As you can see, it's running fine on Linux but it fails on Windows: https://github.com/ggrossetie/testcontainers-node-windows/actions/runs/16575193079/job/46877612649

Hi @ggrossetie, AFAIK the windows GHA runners don't support running Linux containers (you are trying to run Redis).
LMK if I'm missing something and I'll re-open the issue.

Yes, you are right: https://github.com/orgs/community/discussions/25491
That's a serious limitation 😞

Do you think it would be possible to report the actual cause? The current error message is not really helpful.
