How to differentiate an defer interaction

Hi I would like to know how I can differentiate the method used to defer the interaction since there is deferReply and deferUpdate. Is it even possible ? If yes, how because I only see one property deferred set to true by both of the method ? NodeJS : 18.x DiscordJS: 14.14.1

- What's your exact discord.js npm list discord.js and node node -v version? - Not a discord.js issue? Check out #other-js-ts. - Consider reading #how-to-get-help to improve your question! - Explain what exactly your issue is. - Post the full error stack trace, not just the top part! - Show your code! - Issue solved?

I'm not entirely sure why you need to, whats your situation?

Ok, I will try to explain it : I listen to the "interactionCreate" event and call a function that depends on the ID of the button clicked. This function performs various tasks and may generate an error (unauthorized user, invalid parameter, etc.). This error is taken into account in the interaction creation event to send a response to the user, informing them of the system's status. But when the function throws an error and I catch it, I call editReply or reply depending on the deferred property to display the error message. There are three possible scenarios: - The function has never called a defer method: the behavior is correct. - The function called deferReply() before throwing an error: the behavior is correct. - The function called deferUpdate() before throwing an error: the initial message is updated with the error message, whereas I'd like to keep it and send another message containing the error. I can provide you a little piece of code if it can help you 👍

Gotcha, thanks Whats the behaviour if you use followUp instead

If I use followUp the behavior after a deferUpdate is good (this is what I want) but not after a deferReply :/ I would like to keep using editReply() after a deferReply but I would like to use followUp() after deferUpdate. Here is a little piece of code that can help to understand the problem:

if (!interaction.isButton()) {
    throw new Error("The interaction is not a button.")
}

try {
    await InteractionService.buildActionFromInteraction(interaction)
        .execute(client, interaction);
} catch (e: any) {
    if (!interaction.replied && !interaction.deferred) {
        return interaction.reply({ content: e.message });
    } else if (interaction.replied) {
        // I would like to fall here after a deferUpdate() also
        return interaction.followUp({ content: e.message });
    } else {
        return interaction.editReply({ content: e.message });
    }
}

if (!interaction.isButton()) {
    throw new Error("The interaction is not a button.")
}

try {
    await InteractionService.buildActionFromInteraction(interaction)
        .execute(client, interaction);
} catch (e: any) {
    if (!interaction.replied && !interaction.deferred) {
        return interaction.reply({ content: e.message });
    } else if (interaction.replied) {
        // I would like to fall here after a deferUpdate() also
        return interaction.followUp({ content: e.message });
    } else {
        return interaction.editReply({ content: e.message });
    }
}

To be a little more precise for this:

but not after a deferReply

It's because, DiscordJS throw an error if you are using followUp without a full reply Maybe it could be interesting to add two property: - updateDeferred - replyDeferred And change the deferred property to a getter equal to updateDeferred || replyDeferred Suggestion added in #Split "deferred" property in Interaction class in two, to better reflect previous actions in case there is no other way to do it I forgot to answer and you was right, I don't know why in my previous tests the result was different For real, I know: the problem was me and I surely made an error in my code 😂
