So what happens is I am creating a discord bot that access the routes from express and it works if I keep it on a certain server, but if I try to access express on a different server while the server is on I get
Restarting the server removes the "assignments is not a function" So this only works when I try to access these routes endpoints from a completely different server. More information, If I try to do curl requests to these endpoints with different channel or guild id information, I also get that error. So I am assuming thats where a lot of the problem is coming from. I don't know why different information throws off the function.
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);});

CodePudding user response：
The problem lies in the fetchCall.js file. First of all, you are exporting things in the wrong manner. If you are not using tools like babel, syntax export function ... is incorrect, you have to use module.exports to export things from a Node.js module.
So you can change your file in the following manner, for example.
function discussions(guild, channel) {
guildid = guild;
channelid = channel;
discussionsFunc();
async function discussionsFunc() {
try {
updateChannelID(guildid, channelid);
await getRecord({
guild_id: `${guildid}`
}, getFetchData);
const res1 = await fetch(url `courses/${course}/discussion_topics?scope=unlocked`, {
method: "GET",
headers: {
Authorization: `Bearer ${access_token}`,
"Content-Type": "application/json",
},
});
const apiData = await res1.json();
for (discussions of apiData) {
const string = ["**TOPIC: " discussions.title "**", discussions.message "\n"];
const res2 = await fetch(
`https://discordapp.com/api/channels/${channelid}/messages`, {

"Authorization": `Bot ${config.TOKEN}`,

"Content-Type": "application/json",
},
"Connection": "close",
body: JSON.stringify({
content: string.join('\n').replace(/(<([^>] )>)/gi, "")
}),

const apiResponse = await res2.json();

}
module.exports = {assignments, discussions, announcements}
Also another advice to rename your functions, functions are verbs, not nouns, e.g. instead of assignments name it getAssignments or whatever it is doing.
UPD:
And looks like you are using wrong modules, Node.js uses CommonJS modules, so you have use require to import other modules unless you are using TypeScript or Babel.
Change your index.js file to
const express = require('express');
const{ assignments , announcements , discussions}
= require("./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);});
