How to create cardano light wallet?

Question

I am trying to create light wallet of cardano. these are steps I followed but not able to create it. It create only full node wallet.

METHOD 1 first I run full node

cardano-node run \
    --topology /root/cardano-node/mainnet-topology.json \
    --database-path /root/cardano-node/db/ \
    --socket-path /root/cardano-node/node.socket \
    --host-addr 127.0.0.1 \
    --port 1225 \
    --config /root/cardano-node/mainnet-config.json

then connected with node using cardano wallet

cardano-wallet serve \
    --port 8090 \
    --mainnet \
    --database /root/cardano-node/db \
    --node-socket /root/cardano-node/node.socket

then create wallet using cardano-wallet wallet create from-recovery-phrase mytwallet but this generates only full node wallet. please correct me if i am doing something wrong.

METHOD 2 by using blockfrost api and IOHK github cardano-wallet binaries I able to connect with blockfrost but not able to create light wallet. IOHK - https://input-output-hk.github.io/cardano-wallet/user-guide/cli

cardano-wallet serve --light --blockfrost-token-file /root/blockfrost-mainnet.key --mainnet --port 8090 cardano-wallet wallet create from-recovery-phrase mytwallet

after this I got error something like this

Answer 1

My apologies for the error you see in the --light mode. Its just not ready to be used yet, we're working on it.
