javascript - Showing error during using overwritepermission

Question

I was expecting to give everyone 10 sec to type and then remove the permission but the script is not working.

if (message.channel.id === "channel id") {
    if (!message.member.roles.cache.has("everyone's id")) {
        setInterval(function () { 
            message.channel.send("start").then(channel => {
                channel.overwritePermissions([{
                    id: message.guild.id,
                    allow: 0x00000800
                }]).then(channel => {
                    setTimeout(function () {
                        channel.overwritePermissions([{
                            id: message.guild.id,
                            deny: 0x00000800
                        }])                        
                    }, 10000);
                });   
            })
        }, 5000);
    }
}

This error is showing in the terminal.

The channel.send() function returns a Message not a Channel. The correct code would be:

.then(() => {
    message.channel.overwritePermissions([
    {
      id: message.guild.id,
      allow: [0x00000800]
    },
])
