SlashCommand interaction is undefined

Hey, I just encountered an Error I can't explain... I get an error every time I execute an SlashCommand from my Bot telling me "interaction" is undefined. I haven't changed anything in my App for a couple of weeks, so I can't tell when this error started to occur. Things I've checked: - if discord.js has a newer version that i can install - already had the latest version 14.16.3 - I republished my SlashCommands to Discord - still not working This is an example breakdown of a command in my Application:

module.exports = {
  data: new SlashCommandBuilder()
    .setName('joke')
    .setDescription('Tells a Joke!'),
  async execute(interaction: CommandInteraction) {
    await interaction.deferReply({ ephemeral: false }) // this line already throws the error
    // here is just some code to response
  }
};

module.exports = {
  data: new SlashCommandBuilder()
    .setName('joke')
    .setDescription('Tells a Joke!'),
  async execute(interaction: CommandInteraction) {
    await interaction.deferReply({ ephemeral: false }) // this line already throws the error
    // here is just some code to response
  }
};

Here is the Stacktrace (I edited the path to make it more readable)

Sure, I just found something there that could cause the issue, I'll check that first 👍

Okay, that was not the Issue ... interactionCreate.ts

module.exports = {
  name: Events.InteractionCreate,
  async execute(interaction: Interaction) {
    if (!interaction.isChatInputCommand()) return;
// SmeetaClient#commands is typed the following: 
// public commands: Collection<string, ExportedSlashCommand>;
// I checked and can confirm the Collection is filled as it should be
    const command = (interaction.client as SmeetaClient).commands.get(interaction.commandName);

    if (!command) {
      console.error(`No command matching ${interaction.commandName} was found.`);
      return;
    }

    try {
      await command.execute();
    } catch (error) {
      console.error(error);
      if (interaction.replied || interaction.deferred) {
        await interaction.followUp({ content: 'There was an error while executing this command!', ephemeral: true });
      } else {
        await interaction.reply({ content: 'There was an error while executing this command!', ephemeral: true });
      }
    }
  },
};

module.exports = {
  name: Events.InteractionCreate,
  async execute(interaction: Interaction) {
    if (!interaction.isChatInputCommand()) return;
// SmeetaClient#commands is typed the following: 
// public commands: Collection<string, ExportedSlashCommand>;

    const command = (interaction.client as SmeetaClient).commands.get(interaction.commandName);

    if (!command) {
      console.error(`No command matching ${interaction.commandName} was found.`);
      return;
    }

    try {
      await command.execute();
    } catch (error) {
      console.error(error);
      if (interaction.replied || interaction.deferred) {

Ohh whoops you are right ... I'm wondering how this was working before 😅

We highly recommend you extend the Client structure properly instead of just attaching custom properties like .commands to the regular discord.js Client instance. - Using typescript, you might want to consider casting or augmenting the module type

Yeah that was the issue 😄 the typing of the execute function was wrong thats why I haven't noticed the issue there It's working now, thanks for your quick help! ❤️
