How should I use the wallet after I start btcwallet [-4: blockchain RPC is inactive]

[BlueShells]

I have successfully set up an btcd with segtest , and I want to create some new blocks

So I follow the guide , create a new wallet with command

btcwallet -u rpcuser -P rpcpass --create

and started it

./btcwallet -u test -P "test" --rpclisten 0.0.0.0:18332 --testnet --debuglevel=trace --rpcconnect https://btcd:18334 --cafile rpc.cert

but I failed to get newaddress with command

./btcctl --wallet -u test -P "test" --testnet getnewaddress

I got "-4: blockchain RPC is inactive"

but if I run the same command with "listaccounts"

./btcctl --wallet -u test -P "test" --testnet listaccounts

I could get
{ "default": 0, "imported": 0 }

so I tmp unlock this wallet
./btcctl --wallet -u test -P "test" --testnet walletpassphrase test 30

then I could create wallet

./btcctl --wallet -u test -P "test" --testnet createnewaccount abc

and I got this error when create address
./btcctl --wallet -u test -P "test" --testnet getnewaddress abc legacy
