On-premise demo of ERPNext

I try to install on-premise demo of ERPNext (v11.1.4):

bench new-site demo.local

bench --site demo.local install-app erpnext

bench --site demo.local execute erpnext.demo.demo.make

bench --site demo.local execute erpnext.demo.demo.simulate

And get the exception 1:

After rerun again 1-2-1 etc.
Demo looks like working but I’m not sure about the integrity of the demo data.
