Question

所以我我做了一个天气命令，但是当用户放到某个位置时，它会向我发送一条错误命令，而我的错误是告诉我当用户不放置位置时是否找不到长度

else if (command === 'weather') {
         weather.find({search: args.join(" "), degreeType: "C"}, function(err, result) {
        if(err) message.channel.send(err)

        if(result.length === 0) {
            message.channel.send("**please enter a valid location**")
            return;
        }

        var current = result[0].current 
        var location = result[0].location 

        let embed = new Discord.MessageEmbed()
           .setDescription(`**${current.skytext}**`) 
           .setAuthor(`Weather for ${current.observationpoint}`) 
           .setThumbnail(current.imageUrl) 
           .setColor("RANDOM") 
           .addField("Timezone", `UTC${location.timezone}`, true) 
           .addField("Degree Type", location.degreetype, true) 
           .addField("Temperature", `${current.temperature}`, true)
           .addField("Feels like", `${current.feelslike} Degrees`, true)
           .addField("Winds", current.winddisplay, true)
           .addField("Humidity", ` ${current.humidity}%`, true)
           .addField("Day", `${current.day}`, true)
           .addField("Date", `${current.date}`, true)
           
           message.channel.send(embed)```
