TypeError // Text mirror command not working

Hello, so I'm trying to create a command that mirrors the text the user inputs, the only problem I have is I can't find a way to create an option for the user to input text in, and I get this error message when I run the command: 
    this.ephemeral = options.ephemeral ?? false;
                             ^

TypeError: Cannot read properties of null (reading 'ephemeral')
    this.ephemeral = options.ephemeral ?? false;
                             ^

TypeError: Cannot read properties of null (reading 'ephemeral')
Relevant index.js code 
client.on('interactionCreate', (interaction) => {
    if (!interaction.isChatInputCommand()) return;

    const interactionChannel = interaction.channel;

    if (interaction.commandName === 'mirror') {
        const mirrorMessage = interaction.options.get('mirror-message');
        interaction.reply(mirrorMessage);
    }
client.on('interactionCreate', (interaction) => {
    if (!interaction.isChatInputCommand()) return;

    const interactionChannel = interaction.channel;

    if (interaction.commandName === 'mirror') {
        const mirrorMessage = interaction.options.get('mirror-message');
        interaction.reply(mirrorMessage);
    }
Relevant register-commands.js code 
    {
        name: 'mirror',
        description: 'mirrors your text',
        options: [
            {
                 name: 'mirror-message',
                 description: 'テキスト',
                 type: ApplicationCommandOptionType.String,
                 required: true,
            },
        ]
    },
    {
        name: 'mirror',
        description: 'mirrors your text',
        options: [
            {
                 name: 'mirror-message',
                 description: 'テキスト',
                 type: ApplicationCommandOptionType.String,
                 required: true,
            },
        ]
    },
I have tried to research in the Discord.JS documentation, but it's really cryptic and hard to understand (as I'm a beginner), thank you in advance.

Hey, that's the commands array I don't know if I'm not asking for help correctly as I've read the guidelines and made my own research & troubleshooting beforehand, but I just can't pin this one down, and it's frustrating because it's such an incredibly simple feature I'm trying to code all I want to do is ask the user for input and give that input a name when creating a command
