Error: Child process exited with code 1

Expected Behavior

This should not fail, I guess we could have a fallback logic that intercepts the error and bumps the deployment tx fee

Current Behavior

Deploying tokens fail

This is somehow fixed after a zk clean + zk reinit. While this does not address the core issue, I think this is a good enough solution for now.
