While working on a Discord bot that accesses routes from Express, I encountered an issue. It seems to function properly when kept on a specific server, but if I try accessing Express on a different server while it's running, I encounter the error "assignments is not a function". This error disappears upon restarting the server, indicating that it only occurs when trying to access these route endpoints from another server with different information such as channel or guild id. The discrepancy in information seems to be causing this problem, though the exact reason remains unclear.
index.js
import express, { json, query, request, response } from 'express';
import { assignments , announcements , discussions} from "./Fetch/fetchCalls.js";
var app = express();
app.use(express.json());
const PORT = 8080;
app.listen(PORT);
var guild;
var channel;
app.all('/assignments',(request) => {assignments(guild = request.body.guild, channel = request.body.channel);});
app.all('/discussions',(request) => {discussions(guild = request.body.guild,channel = request.body.channel); });
app.all('/announcements', (request) => {announcements(guild = request.body.guild,channel = request.body.channel);});
fetchCalls.js
import fetch from 'node-fetch';
import { createRequire } from "module";
import { getRecord, updateChannelID } from './dbUtil.js';
import { clearData } from './clear.js';
const require = createRequire(import.meta.url);
const config = require("../Canvas Bot/Source/Data/config.json")
//functions for fetching data and sending announcements, discussions, and assignments
export function discussions(guild, channel) {
//function implementation
}
export function announcements(guild, channel) {
//function implementation
}
export function assignments(guild, channel) {
//function implementation
}
function getFetchData(document) {
obj = 'course_' + document._courseid;
course = document._courseid;
course1 = "_" + course;
url = 'https://' + document.prefix + '.instructure.com/api/v1/';
access_token = document.access_token;
console.log('obj = ' + obj + '\ncourse = ' + course + '\nurl = ' + url + '\naccess_token = ' + access_token);
}
If needed:
dbUtil.js
import { MongoClient } from 'mongodb';
//update channel ID function
export async function updateChannelID(guildids, channelids) {
try{
await client.connect();
const database = client.db("Users");
const docs = database.collection("user_info");
var query = {guild_id: `${guildids}`};
var insert = {$set: {channel_id: `${channelids}`}};
docs.updateOne(query,insert);
}
catch(error){
console.log(error);
}
}
