I'm getting and unhandled promise rejection that I need correct syntax for in nodejs

I've created a module that is pulling data from binance us api, but I can't seem to send that variable to any other file properly. I'm trying to create a function that pulls a variable each time it runs and send it to be used as a dynamic variable in another file.

This is my updated function code from discussions below in /modules/Tradepair.js:

async function getTradepair() {
  const apiUrl = "https://api.binance.us/api/v3/ticker/24hr";
  // Make a GET request
 let data ;
 try{
    const response = await fetch(apiUrl);
    if (!response.ok) {
       throw new Error("Network response for pair was not ok");
    }
     data = await response.json();
    //  console.log(data);

 } catch (error) {
     console.error('There was a problem with the fetch operation:', error);
}
  const max = data.reduce(
      (a, b) => (a.priceChangePercent > b.priceChangePercent ? a : b), data[0]);
  console.log(`Max Symbol from API: ${max.symbol}`);
  console.log(`Max Percent from API: ${max.priceChangePercent}`);
  const tradingPair = max.symbol;
  console.log(`Assigned to Trading pair variable: ${tradingPair}`);
  return tradingPair; // Return the tradingPair variable
}
module.exports = getTradepair;

This is the updated version from discussions below:

require("dotenv").config();
const Wolf = require("./modules/Wolf.js");
const getTradepair = require("./modules/Tradepair.js"); //file-name where you have defined this `getTradepair()` function.

async function getData() {
  try {
    const data = await getTradepair();
    console.log("From index:" + " " +data);
    return data;
  } catch (error) {
    console.error("Error fetching data:", error);
  }
}

const config = {
  // tradingPair: process.env.TARGET_ASSET + process.env.BASE_ASSET,
  tradingPair: getData(),
  profitPercentage: Number(process.env.PROFIT_PERCENTAGE) / 100,
  budget: Number(process.env.BUDGET),
  compound: process.env.COMPOUND.toLowerCase() === "true",
  profitLockPercentage: Number(process.env.PROFIT_LOCK_PERCENTAGE) / 100,
  stopLimitPercentage: Number(process.env.STOP_LIMIT_PERCENTAGE) / 100,
};

const wolf = new Wolf(config);

And this is the error I keep getting:

Max Symbol from API: VITEUSDT
Max Percent from API: 6.467
Assigned to Trading pair variable: VITEUSDT
From index: VITEUSDT
node:internal/process/promises:289
            triggerUncaughtException(err, true /* fromPromise */);
            ^

Before the Promise gets resolved this getData() is executed in a synchronous manner which is not a valid practice and that is why you are seeing this error.

After defining the getTradepair() as an async function import and execute this function like this.

const getTradepair = require('./modules/your-file-name'); //file-name where you have defined this `getTradepair()` function.

async function getData(){

 try {
        const data = await getTradepair();
        console.log(data);
        return data ;
     } catch (error) {
        console.error('Error fetching data:', error);
     }

 }

 getData().then((data) => {

   const config = {
     // tradingPair: process.env.TARGET_ASSET + process.env.BASE_ASSET,
     tradingPair: data,
     profitPercentage: Number(process.env.PROFIT_PERCENTAGE)/100,
     budget: Number(process.env.BUDGET),
     compound: process.env.COMPOUND.toLowerCase() === "true",
     profitLockPercentage: Number(process.env.PROFIT_LOCK_PERCENTAGE)/100,
     stopLimitPercentage: Number(process.env.STOP_LIMIT_PERCENTAGE)/100

   };

   const wolf = new Wolf(config);

   console.log(wolf); // you can also console to see your expected result 

  } ).catch((error) => {

     console.error("Error:", error);

  });

Try the above code.I am sure you will not get this UnhandledPromiseRejection error. Still if it doesn't go along the way then please don't bother to ask for help.
