Bot sends DM to me and then crashes in client.on('message'

    let me = message.guild.members.cache.get('MyId');    if(message.content.includes('Ping!')) {        me.send('Pong!')    return;    }

I've tried replacing me.send with message.channel.send two times, one excluding the 'let me' code and one including the 'let me' code, both times it worked fine
