I am not sure if this is still relevant but please try the following:

1. Ensure that you have enough disk space available (>6 GB for High Sierra).
2. Put the script in a known folder such as Desktop and then execute it.
3. If that still doesn't work, download the installation image from the App Store again.

Let me know if it still doesn't work and I will try to investigate what's going on. Cheers!

Hi @wolfferine,

It seems like that the script is failing at

asr restore -source "${INPUT_MOUNT}/BaseSystem.dmg" -target "${BUILD_MOUNT}" -noprompt -noverify -erase

At first glance, I think this has something to do with BaseSystem.dmg file. Could you trying manually deleting the BaseSystem.dmg file and then running the script again?

I unfortunately do not have a macOS system handy with me to test it out.
