What's the best way to reproduce the error?

Could you list the commands please?
I ran zk init as usual with no errors

Try zk init and make sure to delete previous docker volumes (db and geth) or other previous data folders

you will see this error

The reason is that you can not setup server genesis before the l1 smart contracts are deployed
