Error joining pool using CLI, PoolWallet is required

Got this error

Error performing operation on Plot NFT -f xxxxxx wallet id: 2: {‘error’: ‘wallet id 2 is of type NFTWallet but type PoolWallet is required’, ‘success’: False}

Command used is

chia plotnft join -i 2 -f xxxxxx -u https://asia1.pool.space -y

Chia version is 1.7.1
How do I fix this?
