Hi @jiguantong thanks for reporting! I'm trying to reproduce this error and will keep you posted of any findings. Stay tuned!

This is a known bug and is because the tutorials contain an outdated command. See this Discord post and context around it. There are probably multiple workarounds, but the one I suggested where you run the other command and simply copy the bytecode into the contract worked for me.

I wasn't aware of this bug.

Solved in version 0.9.10 which will be live on npm in a few minutes. @jiguantong kindly confirm that it works on your side by upgrading the package version and retrying.

Thanks, I will try it tomorrow.
