unknown webhook errors discord http bot

Hey guys, I have a http only bot running on a cf worker and im running into random Unknown webhook problems, mainly for my /meme command, and I have no idea what's wrong or where to go to fix it. Here's the code for my /meme command: https://sourceb.in/yrwYOIxtyS The command "handler": https://sourceb.in/pzY6NMCBQt In my index.ts I just have this https://sourceb.in/n6o9OX2kRH which is just a switch case over all of the types, simple stuff. I believe it's because im trying to "editReply" before the deferReply has "resolved", but im wondering what I can actually do to help this. I have a button too, which this happens with, basically the same code though. Thanks.

what's the exact error?

gwapesOP•5mo ago

From discord it’s just the code and the message being unknown webhook, let me grab it again { message: 'Unknown Webhook', code: 10015 } Idk if I’ve done something funky in my project, probably that

Walshy•5mo ago

that sounds like your webhook url is invalid

gwapesOP•5mo ago

It doesnt happen all of the time either. One of the mods in ddevs said it could be the worker taking too long to respond but idk If it was invalid it would happen all the time?

Walshy•5mo ago

const webhookUrl = https://discord.com/api/v10${Routes.webhookMessage(env.discord_application_id, interaction.token, '@original')};

so i would print this out and check what it's returning

gwapesOP•5mo ago

I removed the “env.discord_application_id” and pasted it with my app id for testing and got the same thing, so I’m sure it isn’t that Routes is from discord-api-types to make the url

What do you see on Discord? Do you see the message like "App is thinking..." or something similar?

gwapesOP•5mo ago

Yh, it does successfully defer and then I get the unknown webhook error

D Trombett•5mo ago

The fact that you're saying that it sometimes works confuses me I think that something is wrong with the fetch calls Like, you're not always passing the content type header and never passing your token tbh I would suggest you using @discordjs/rest to make API calls to discord as it handles everything What I do is creating a rest.ts file with this content (the hash and handler options were required to make it work in Workers, not sure if they've fixed it now):

import { REST } from "@discordjs/rest";
import { APIVersion } from "discord-api-types/v10";

export const rest = new REST({
    version: APIVersion,
    hashSweepInterval: 0,
    handlerSweepInterval: 0,
})

import { REST } from "@discordjs/rest";
import { APIVersion } from "discord-api-types/v10";

export const rest = new REST({
    version: APIVersion,
    hashSweepInterval: 0,
    handlerSweepInterval: 0,
})

And at the start of the fetch server handler I call rest.setToken(env.DISCORD_TOKEN). Then I use the rest whenever I need it by importing it, like in my ping command:

await rest.patch(
    Routes.webhookMessage(interaction.application_id, interaction.token),
    {
        body: {
            content: `🏓 **Pong!** ...`,
        } satisfies RESTPatchAPIWebhookWithTokenMessageJSONBody,
    },
)

await rest.patch(
    Routes.webhookMessage(interaction.application_id, interaction.token),
    {
        body: {
            content: `🏓 **Pong!** ...`,
        } satisfies RESTPatchAPIWebhookWithTokenMessageJSONBody,
    },
)

You don’t need to pass the token for an editReply, https://github.com/discordjs/discord.js/blob/main/packages/discord.js/src/structures/Webhook.js#L341 Ig the only thing I can see now is that they pass the interaction id?

Nvm they don’t it’s still the app id

gwapesOP•5mo ago

I mean I can try using that, I was just going more simply and using fetch

D Trombett•5mo ago

Mmh, it's strange because I just tried and it gave me an error about not passing the token

gwapesOP•5mo ago

With the editReply route? I mean either way, that’s not my issue since it doesn’t error either unauthorised I mean I can pop it in there I need to spin up some code using a library or something, my handling is probably wrong Also would be good to point out that it only ever happens when you spam it. It seems to happen in servers more often then it does in the dms of the bot

D Trombett•5mo ago

ah then maybe the defer takes too long to arrive and the edit is impossible as the webhook is deleted after 3 seconds if you don't defer in time

gwapesOP•5mo ago

But aren’t cf workers like hella quick on getting the response out? That’s basically the only thing I can think of that makes sense here. The webhook token is invalid 15 mins, or you edit before the defer has been “validated”? That’s why you await a deferReply if you’re using something like djs

ManaGeorge•5mo ago

It sounds possible that the worker isn’t scaling at the request load you get, causing delays in acking the newer requests coming out of discord. (I’m not familiar with how workers scale.) I didn’t experience that exactly but had some similar response issues, I ended up splitting my bot into two workers, one that acks then passes the interaction to a queue and another that consumes the queue messages and actually processes the interaction

D Trombett•5mo ago

I'm not sure if there is a limit of how many requests can be handled at the same time, because in that case maybe the worker may be waiting for other contexts to be closed before starting to handle the request

gwapesOP•5mo ago

I may see if using a library helps. As maybe I’ve done something wrong. Just a bit busy atm but I appreciate all of your responses!
