我不能发送整段代码，但我相当确定这部分会导致错误：
function send_log(guildId, embed) {
logSchema.findOne({ Guild: guildId }, async (err, data) => {
if (!data || !data.Channel) return;
const LogChannel = client.channels.cache.get(data.Channel);
if(LogChannel) return;
embed.setTimestamp();
try {
LogChannel.send({ embeds: });
} catch(err) {
console.log(err);
}
});
}
我遇到了_patch()函数的问题，所以我将其注释掉，现在可以运行，但我不知道如何修复这个。我知道Mongoose自5.0版本起不再支持回调函数。

I cannot send the whole code but i'm pretty sure this part is giving error:
function send_log(guildId, embed) {
logSchema.findOne({ Guild: guildId }, async (err, data) => {
if (!data || !data.Channel) return;
const LogChannel = client.channels.cache.get(data.Channel);
if(LogChannel) return;
embed.setTimestamp();
try {
LogChannel.send({ embeds: });
} catch(err) {
console.log(err);
}
});
}
i was having trouble with _patch() function so i just commented that part out and now it works but
idk how to fix this one. I know that Mongoose just dropped support for callbacks from its node.js driver as of version 5.0. but idk how to

根据错误信息，findOne 方法不再接受回调参数。
你可以使用 async await 来替代：
async function send_log(guildId, embed) {
try {
const data = await logSchema.findOne({ Guild: guildId });
if (!data || !data.Channel) return;
const LogChannel = client.channels.cache.get(data.Channel);
if (!LogChannel) return;
embed.setTimestamp();
LogChannel.send({ embeds: [embed] });
} catch (err) {
console.log(err);
}
}

As stated by the error, the [`findOne`][1] method no longer accepts a callback parameter.
You can just use `async await`:
async function send_log(guildId, embed) {
try {
const data = await logSchema.findOne({ Guild: guildId });
if (!data || !data.Channel) return;
const LogChannel = client.channels.cache.get(data.Channel);
if (LogChannel) return;
embed.setTimestamp();
LogChannel.send({ embeds: });
} catch (err) {
console.log(err);
}
}
