this is beacuse not all changes were reflected after this ethersphere/bee#1613, and pss was made before #118
also, it seems that pssPublicKey was used here

beekeeper/pkg/check/pss/pss.go

Line 141 in cf7cb22

err = nodeA.SendPSSMessage(ctx, addrB.Overlay, addrB.PSSPublicKey, testTopic, o.AddressPrefix, testData, batchID)

@istae can you double check that test is valid for this SendPSSMessage?

@gacevicljubisa this is the struct on the bee side

type addressesResponse struct {
	Overlay      *swarm.Address        `json:"overlay"`
	Underlay     []multiaddr.Multiaddr `json:"underlay"`
	Ethereum     common.Address        `json:"ethereum"`
	PublicKey    string                `json:"publicKey"`
	PSSPublicKey string                `json:"pssPublicKey"`
}
