Unable to fetch members of a chat

[wengzilla]

For some of my group chats, I'm unable to fetch the member list of the group chat. It does, however, seem to work in the official Telegram Mac App. When I click on group chats where the member list fetch fails, I get the following error in console:

{
    "type": "CHANNEL_INVALID",
    "stack": "Error\n    at ve (https://web.telegram.org/k/mtproto.worker-CA0ZHRcC.js:1:3479)\n    at xd.processError (https://web.telegram.org/k/mtproto.worker-CA0ZHRcC.js:14:587721)\n    at xd.processMessage (https://web.telegram.org/k/mtproto.worker-CA0ZHRcC.js:14:590494)\n    at xd.processMessage (https://web.telegram.org/k/mtproto.worker-CA0ZHRcC.js:14:589417)\n    at xd.processMessage (https://web.telegram.org/k/mtproto.worker-CA0ZHRcC.js:14:588631)\n    at xd.onTransportData (https://web.telegram.org/k/mtproto.worker-CA0ZHRcC.js:14:583727)",
    "message": "CODE#400 CHANNEL_INVALID",
    "originalError": {
        "_": "rpc_error",
        "error_code": 400,
        "error_message": "CHANNEL_INVALID"
    },
    "code": 400
}

Is there an easy fix here?

export function buildInputChat(chatId: string) { return BigInt(chatId); } My solution: export function buildInputChat(chatId: string) { return buildMtpPeerId(chatId, 'chat'); }
