when checking for the number of characters in the argument, I ran into a problem that the bot sends

const { ApplicationCommandOptionType, EmbedBuilder } = require('discord.js');

module.exports = {
    name: "test",
    usage: "/test",
    options: [
        {
            name: 'option',
            description: '43-symbol',
            type: ApplicationCommandOptionType.String,
            required: true
        }
    ],
    category: "test",
    description: "test",
    ownerOnly: false,
    run: async (client, interaction, args) => {

            await interaction.deferReply({ephemeral: true});

            if(!interaction.options.getString("option").lenght !== 43) {
                interaction.editReply({
                    content: `not 43`
                })
            } else {
           
        const embed = new EmbedBuilder()
            .setThumbnail(client.user.displayAvatarURL())
            .addFields([
                {name: `yay`, value: `${interaction.options.getString("option")}`}
            ])
            .setColor('#FF8747')
            .setFooter({

                iconURL: `${client.user.displayAvatarURL()}` 
            });

        return interaction.reply({ 
            embeds: [embed],
