unhandledpromiserejectionwarning error status code 400 || Discord Bot Error

Question

Now im pretty stupid so i dont exactly get coding and what not but i do have some expirence with basic javaS,

so I recently implanted this code and suddenly after every command used I get this error msg unhandledpromiserejectionwarning error status code 400

        if (msg.content.startsWith(`${prefix}`)) {
        let Q5 = msg.content.substr(1);


        async function TOD() {

            var res = await axios.get(`https://api.truthordarebot.xyz/api/${Q5}`);
            var Q1 = res.data.question
            console.log("The TOD Command Was Used")

            const girlEmbed = new Discord.MessageEmbed()
            .setTitle(`***${Q1}***`)
            .setColor(randomHexColor())
            .setFooter(footer)
            msg.channel.send(girlEmbed)

        }

        
        

        TOD()
    }
