Node.js DiscordAPIError:解析ID时通道未知

我正在尝试从已保存的ID获取TextChannel对象-调试表明该ID是从数据库中提取的，并且格式正确，但在尝试运行函数时收到以下错误：

DiscordAPIError: Unknown Channel
at RequestHandler.execute (/home/user/Project/node_modules/discord.js/src/rest/RequestHandler.js:170:25)
at processTicksAndRejections (internal/process/task_queues.js:97:5) {
method: 'get',
path: '/channels/674680371077578800',
code: 10003,
httpStatus: 404
}

代码如下：

const servdata = await Servers.findOne({ where: { servID: message.guild.id}}) //Grabs Servdata for checks
    if (servdata) { //Checks if server has data
        if (servdata.settingUp) { //Handling Welcome Data Entry
            var expectedChannel = await client.channels.fetch(servdata.welcMessChannelID) //Gets the channel our setup message is in
            console.log(expectedChannel)
