Is it possible to integrate a common error handler class?

the best practise is to catch promise rejections when they occur not later on

main method call:

    const deleted = await interaction.channel.bulkDelete(messages, true)
        .catch((err) => errorHandler(interaction, err));

    const deleted = await interaction.channel.bulkDelete(messages, true)
        .catch((err) => errorHandler(interaction, err));

the error handler method:

export async function errorHandler(
    interaction: CommandInteraction,
    error: Promise<Collection<string, Message<boolean> | PartialMessage | undefined>>
): Promise<boolean> {
    console.error("[ERROR]", error);
    if (!interaction.replied && !interaction.deferred) {
        await interaction.reply({
            embeds: [
                new EmbedBuilder()
                    .setColor("#FF0000")
                    .setTitle("❌ Error")
                    .setDescription("An error occurred while executing the command.")
            ],
            flags: MessageFlags.Ephemeral
        });

        return true;
    }

    return false;
}

export async function errorHandler(
    interaction: CommandInteraction,
    error: Promise<Collection<string, Message<boolean> | PartialMessage | undefined>>
): Promise<boolean> {
    console.error("[ERROR]", error);
    if (!interaction.replied && !interaction.deferred) {
        await interaction.reply({
            embeds: [
                new EmbedBuilder()
                    .setColor("#FF0000")
                    .setTitle("❌ Error")
                    .setDescription("An error occurred while executing the command.")
            ],
            flags: MessageFlags.Ephemeral
        });

        return true;
    }

    return false;
}

would this be considered the good practice? then in this case idk how I exit the method above if an error has occurred unless I use a try-catch block :Thinkfusing: I can put more details into the message yes. currently my main concern is what the best way to handle errors is. I don't want to copy and paste the method above for each method that can fail, or wrap the whole function with a try-catch block I can simply forward the message in the error promise, no?

.setDescription("An error occurred while executing the command:

.setDescription("An error occurred while executing the command:

" + error + "

")

")

hmmm....
