[Bug]: InvalidOperationException in IDiscordInteraction.RespondAsync (New Issue)

Check The Docs

• I double checked the docs and couldn’t find any useful information.

Verify Issue Source

• I verified the issue was caused by Discord.Net.

Check your intents

• I double checked that I have the required intents.

Description

It was working fine until earlier today: it stopped working with no code change at all. I have updated to the very latest Discord.Net Nuget package (3.10.0), and the issue still occurs, so I assume that something has changed in Discord’s API.

Version

3.10.0

Working Version

3.10.0

Logs

An exception of type System.InvalidOperationException has occurred. Stack trace:

Sample

Code that causes it

        public static async Task RespondWithEmbedAsync(this IDiscordInteraction interaction, string message, Color? color = null, bool ephemeral = false)
        {
            var embed = new EmbedBuilder()
                .WithDescription(message)
                .WithColor(color ?? Color.Red)
                .Build();
            
            await interaction.RespondAsync(embed: embed, ephemeral: ephemeral);
        }

I have also tried without embed, same result:

        public static async Task RespondWithEmbedAsync(this IDiscordInteraction interaction, string message, Color? color = null, bool ephemeral = false)
        {
            //var embed = new EmbedBuilder()
            //    .WithDescription(message)
            //    .WithColor(color ?? Color.Red)
            //    .Build();
            //
            //await interaction.RespondAsync(embed: embed, ephemeral: ephemeral);

            await interaction.RespondAsync(message);
        }

The exception thrown should also have a Message property Could you post the message here?

I studied the Discord.NET source code and found the solution:

UseInteractionSnowflakeDate = false

In the DiscordSocketConfig.

If anyone else is wondering: if you change your computer date and time, you need to set that to false otherwise the “DateTime.UtcNow” won’t match the snowflake correctly.
