Wallet Info doesn't have any pk

I just try getting started on bombay-12 testnet (A Tour of Jigu | Jigu Documentation)

but this code doesn’t work.

tx = wallet.create_and_sign_tx(send, memo="Hello Jigu!", fee=fee)

because wallet.info doesn’t have a public_key in auth.py
it only response this one.

{'type': 'core/Account', 'value': {'address': 'terra1357pf4sr02479wl8mn9tjkt84pcgleasatsy7x', 'account_number': '69136'}}
