wallet publicKey is null

[chain-cpu]

I connected to phantom wallet.

And then I try to get wallet by below code

const wallet = useWallet();

but wallet.publicKey is null.

I am not sure if this is a bug or I use this in a wrong way.

This is almost always because you don't have the React context set up properly: https://github.com/solana-labs/wallet-adapter/blob/master/FAQ.md#-is-not-a-function---is-undefined--uncaught-typeerror-cannot-destructure-property--uncaught-in-promise-walletnotconnectederror

Please follow the setup code here: https://github.com/solana-labs/wallet-adapter#setup
