Discord Bot - Issues responding to interactions

Hello 👋 I can't seem to get my Convex endpoint to respond to my interactions and I have no idea why. Going by the below code any interaction should be met with a message response of Blah however, I just get an empty response (shown in attached image).

const discordRoute = httpAction(async (ctx, request) => {
  console.log("Received request");
  const { isValid, interaction } = await verifyDiscordRequest(request);

  console.log("Is request valid", isValid);

  if (!isValid || !interaction)
    return new Response("Bad request signature.", { status: 401 });

  if (interaction.type === InteractionType.Ping)
    return new Response(
      JSON.stringify({
        type: InteractionResponseType.Pong,
      }),
      { status: 200 },
    );

  console.log("Got here");
  console.log("interaction type", interaction.type);

  if (interaction.type === InteractionType.ApplicationCommand) {
    return new Response(
      JSON.stringify({
        type: InteractionResponseType.ChannelMessageWithSource,
        data: { content: "Blah" },
      }),
      { headers: { "Content-Type": "application/json" }, status: 200 },
    );
  }
  return new Response("Unknown request", { status: 500 });
});

http.route({
  path: "/discord",
  method: "POST",
  handler: discordRoute,
});

const discordRoute = httpAction(async (ctx, request) => {
  console.log("Received request");
  const { isValid, interaction } = await verifyDiscordRequest(request);

  console.log("Is request valid", isValid);

  if (!isValid || !interaction)
    return new Response("Bad request signature.", { status: 401 });

  if (interaction.type === InteractionType.Ping)
    return new Response(
      JSON.stringify({
        type: InteractionResponseType.Pong,
      }),
      { status: 200 },
    );

  console.log("Got here");
  console.log("interaction type", interaction.type);

  if (interaction.type === InteractionType.ApplicationCommand) {
    return new Response(
      JSON.stringify({
        type: InteractionResponseType.ChannelMessageWithSource,
        data: { content: "Blah" },
      }),
      { headers: { "Content-Type": "application/json" }, status: 200 },
    );
  }
  return new Response("Unknown request", { status: 500 });
});

http.route({
  path: "/discord",
  method: "POST",
  handler: discordRoute,
});

My log output looks like,

'Received request'
log
'Is request valid' true
log
'Got here'
log
'interaction type' 2

'Received request'
log
'Is request valid' true
log
'Got here'
log
'interaction type' 2

I cannot see any issues with my Discord bot permissions either. Any help would be much appreciated!

If you’re using the JS discord-interactions library, I think the interaction types are InteractionType.APPLICATION_COMMAND. In terms of debugging, adding some more log lines (maybe right before returning the response) could help?

@k.yr is it possible to "curl" or use the logs to see the raw HTTP output from your convex function and then compare that to the output from a known good HTTP output and see where the difference lies? could it possibly be a CORS issue?

Thanks for the help all! @sshader I'm using the discord-api-types library which has different case for their types. I added another log line but still no luck :/ @mikeysee I added some CORS headers and still no luck. I will try and poke the Convex endpoint a bit more so I can see the HTTP outputs like you suggested 🤔 If I just post a message to a channel that works fine its responding to the interaction that is the issue I think? For example the below code correctly posts a message of "Blah" in the channel the interaction is instigated

const sendMeAMessage = httpAction(async (ctx, request) => {
  console.log("Received request");

  const interaction: APIBaseInteraction<any, any> = await request.json();

  if (interaction.type === InteractionType.ApplicationCommand)
    await discordRequest({
      endpoint: DiscordAPI.createChannelMessage(
        interaction.channel?.id as string,
      ),
      method: "POST",
      body: { content: "Blah" },
    });

  return new Response(null, { status: 200 });
});

http.route({
  path: "/discord",
  method: "POST",
  handler: sendMeAMessage, //discordRoute,
});

const sendMeAMessage = httpAction(async (ctx, request) => {
  console.log("Received request");

  const interaction: APIBaseInteraction<any, any> = await request.json();

  if (interaction.type === InteractionType.ApplicationCommand)
    await discordRequest({
      endpoint: DiscordAPI.createChannelMessage(
        interaction.channel?.id as string,
      ),
      method: "POST",
      body: { content: "Blah" },
    });

  return new Response(null, { status: 200 });
});

http.route({
  path: "/discord",
  method: "POST",
  handler: sendMeAMessage, //discordRoute,
});

hmmm.. I dont know then 😦

I changed the interactions endpoint of another working bot to my new convex one and it worked. Well turns out I somehow had managed to include 'Discord' in the Name of the new bot...removing 'Discord' from the name resolved this issue sigh
