ExpectedConstraintError: Invalid string format discord.js-CodePudding

I am trying to make a slashcommandbuilder for my coinflip command but something is going on. Btw I am new to discord.js. This is the error I get.

return regex.test(input) ? Result.ok(input) : Result.err(new ExpectedConstraintError(type, "Invalid string format", input, expected));
                                                               ^

My code looks like this.

const { EmbedBuilder } = require("discord.js");
const { SlashCommandBuilder } = require('@discordjs/builders');

module.exports = {
  data: new SlashCommandBuilder()
  .setName('coinflip')
  .setDescription('Returns value heads or tails.')
  .addUserOption((option) => option.setName('my guess').setDescription('Enter heads or tails.').setRequired(false)),
  //.addChoices({ name: 'Heads', value: 'guess heads'}, { name: 'Tails', value: 'guess tails'}, { name: 'Other', value: 'You are making a mistake. The chance of this is low.'}),

  async execute(interaction) {
    let coinflip = (Math.random() * 100).toFixed(0) % 2;
    let embedThumbnail = `https://m.media-amazon.com/images/I/51bcZy HZpL._AC_.jpg`;
    console.log(coinflip);
    let result = 'tails';
    if (coinflip == 1){
        result = 'heads';
        embedThumbnail = `https://i.ebayimg.com/images/g/xtcAAOSwLwBaZigS/s-l400.jpg`;
    }
    let guess = interaction.options.getString('my guess');
    let guessedmessage = 'You guessed it correct!'
    if (!result == guess){
        guessedmessage = 'You guessed it wrong, but good try.';
    };

I would appreciate some help in fixing this issue.

CodePudding user response：

The 'my guess' option is a user option, not a string option. Change it to:

.addStringOption((option) => option.setName('my guess').setDescription('Enter heads or tails.').setRequired(false)),
