Unexpected behavior of client.on(Events.VoiceStateUpdate)

I need to check which users are in the channel and which are not after someone leaves. When I subscribe to Events.VoiceStateUpdate and try to console.log the users that are in the channel

client.on(Events.VoiceStateUpdate, (oldState, newState) => {
  console.log(oldState.channel?.members.map((m) => m.id));
  console.log(newState.channel?.members.map((m) => m.id));
}

client.on(Events.VoiceStateUpdate, (oldState, newState) => {
  console.log(oldState.channel?.members.map((m) => m.id));
  console.log(newState.channel?.members.map((m) => m.id));
}

it logs

['1020597576728334398']
undefined

['1020597576728334398']
undefined

Although I was expecting to see this

['1020597576728334398', '546703392081313793']
['1020597576728334398']

['1020597576728334398', '546703392081313793']
['1020597576728334398']

Can you please tell me why this is happening?

Can you log <State>.constructor.name for both oldState and newState?

it is

VoiceState
VoiceState

VoiceState
VoiceState

The situation is like this, there is a bot and 1 user in the channel, when user leaves, I expected to see this

['1020597576728334398', '546703392081313793']
['1020597576728334398']

['1020597576728334398', '546703392081313793']
['1020597576728334398']

1020597576728334398 - is a bot id Okay, thanks a lot, I thought newState.member was the bot itself
