and got:

Thanks!

it says

Failed to get blockNumber from go-ethereum url http://localhost:8545/ [3918 /efcf]

which means it fails to connect to a go-ethereum node. set one up before attempting this.

Also please don't set up a github issues for problems with usage. The discussions tab is probably better suited for this.
