Creating wallet in local node

[CodeWarriorr]

Im running local node and i want to create wallet using RPC but i keep getting errors

curl request

 curl --insecure --cert ~/.chia/mainnet/config/ssl/full_node/private_full_node.crt \
--key ~/.chia/mainnet/config/ssl/full_node/private_full_node.key \
-d '{"":""}' -H "Host: localhost" -H "Content-Type: application/json" -X POST https://localhost:9256/create_new_wallet | python -m json.tool

chia corresponding log

2021-11-13T06:30:51.074 wallet chia.rpc.rpc_server        : WARNING  Error while handling message: Traceback (most recent call last):
  File "/Users/mmach/git/chia-blockchain/chia/rpc/rpc_server.py", line 83, in inner
    res_object = await f(request_data)
  File "/Users/mmach/git/chia-blockchain/chia/rpc/wallet_rpc_api.py", line 446, in create_new_wallet
    host = request["host"]
KeyError: 'host'

How can i effectively create multiple wallets through RPC ?
