Cannot cast [channel_ID] to any kind of InputPeer

[moehmeni]

peerID := -1001187973481 // Already checked it's correct
_, err := client.GetInputPeer(int64(peerID))
if err != nil {
panic(err)
}

panic: cannot cast -1001187973481 to any kind of InputPeer

@rtcq The chat/channel is not yet in cache
To get InputPeer the accesshash of channel should be recived in IncomingUpdates and saved in cache

If the client have already interacted in the chat, remove -100 and try.

I see, so when I want to get a message, what would be the best method to get it directly? my current method is requesting it with channel_ID and message_ID like client.GetMessages(channelID, &telegram.SearchOption{IDs: messageID}) but the availability of the channelID is not guaranteed. Is there any one-time unique identifier for a message to get it from both public and private channels by the client?

If the channel has a username
inputpeer, _ := client.GetSendablePeer("username")

if it's private, wait for NewMessage event and save the chatID and AccessHash from it. Reuse these values in future.

client.AddMessageHandler(telegram.OnNewMessage, func (m *telegram.NewMessage) error {
if m.ChatID() == 108653788..{
println(m.Chat.AccessHash) // m.Channel.AccessHash
})
