I’m looking over the logs for your build. Generally we don’t recommend pre-zipping your projects and instead running butler run a directory that contains your game build (I believe it shows a warning about this).
There’s something about the zip file you’re sending that has an invalid entry and it’s causing the process to abort. I’d have to do more investigation to figure out exactly what’s happening but in the meantime I recommend using butler push
command on a folder, not a zip file.
