Darwinia setup

[Curu24]

Hi,
I'm trying to use this tool for the Darwinia network, but not sure if I set up the config right.
Here's my config file:

[Defaults]
RPCURL = wss://rpc.darwinia.network
Network = darwinia
DepthEras = 10
MinEras = 5
SigningAccount=controller_account_address
SigningMnemonic="word word word word word word word word word word word word"

[darwinia_stash_address]

And this is the error I'm getting:
