Discord js Using guild. but this error happens Cannot read properties of undefined (reading ‘members’)

So I was writing tje code as a test to implement some functionality.

when a user sends a user ID with a command, the bot have to check if the id is on the server or not, but this error occurs Cannot read properties of undefined (reading 'members')

    if (command === "give") {
        message.channel.send('test');
        if (guild.members.cache.find(m => m.id === args)?.id) {
    // true
    message.channel.send('FOUND');
} else {
    // false
    message.channel.send('who is that');
}}

Is there a way to solve the problem or is there another way?
