Why is the system not working?

Question

Node.js

Here is my fs.readDir code:

fs.readdir('./functions/',(err,files)=>{
    if(err) console.log(err);
    let jsfiles = files.filter(f => f.split(".").pop() === "js");
    if(jsfiles.length <=0)console.log("Нет команд для загрузки!!");
    console.log(`Загружено ${jsfiles.length} команд`);
    jsfiles.forEach((f,i) =>{
        let props = require(`./functions/${f}`);
        console.log(`${i+1}.${f} Загружено!`);
        client.commands.set(props.help.name,props);
    })
    });

The question is, why don't the commands work? He sees them, but does not fulfill them.
