Encountering an issue when executing RapidAPI request with async/await

I'm having trouble with a RapidAPI GET request. Every time I try to run it, I get this error:

Uncaught (in promise) ReferenceError: Cannot access ‘getData’ before initialization


Here's my code:

```javascript
const API_KEY = import.meta.env.VITE_API_KEY;
const LOCATION_ENDPOINT = "https://location-checker.example.com/ip/verify?format=json";
const API_HOST = "location-checker.example.com";

const fetchLocationData = async(endpoint, host) => {
  const result = await fetch(endpoint, {
    method: "GET",
    headers: {
      accept: "application/json",
      "x-api-host": host,
      "x-api-key": API_KEY
    }
  });

  if (!result.ok) {
    throw new Error(`Request failed with status: ${result.status}`);
  }

  return await result.json();
}

const executeApiCalls = async() => {
  // GET LOCATION INFO
  const fetchLocationData = await fetchLocationData(LOCATION_ENDPOINT, API_HOST);
  console.log(fetchLocationData);
}

executeApiCalls();

Can anyone spot what I’m doing wrong? I’m new to async/await and promises, so I might be missing something obvious. Thanks for any help!

yo dude, i ran into this same thing last week lol. the other guys are right, ur using fetchLocationData twice. just change the name inside executeApiCalls and ur good to go. like this:

const executeApiCalls = async() => {
const locationStuff = await fetchLocationData(LOCATION_ENDPOINT, API_HOST);
console.log(locationStuff);
}

should work now. good luck!

I’ve encountered similar issues before, and it looks like you’ve got a naming conflict in your code. The problem is that you’re using ‘fetchLocationData’ as both a function name and a variable name within the ‘executeApiCalls’ function.

To fix this, you should rename one of them. I’d suggest keeping the function name as is and changing the variable name in ‘executeApiCalls’. Here’s how you could modify that part:

const executeApiCalls = async() => {
  // GET LOCATION INFO
  const locationData = await fetchLocationData(LOCATION_ENDPOINT, API_HOST);
  console.log(locationData);
}

This should resolve the ‘Cannot access before initialization’ error. The issue was that JavaScript was trying to use the function name as a variable before it was defined, causing the conflict.

Also, make sure your API key and endpoint are correctly set up. Sometimes these kinds of errors can mask other issues with API configuration. If you’re still having trouble after making this change, double-check your API settings and try logging the response at different stages to pinpoint where things might be going wrong.

I see the issue in your code. The problem lies in the scope of your ‘fetchLocationData’ function. You’ve defined it globally, but then you’re trying to reassign it within ‘executeApiCalls’. This causes a temporal dead zone, leading to the error you’re seeing.

To fix this, simply change the variable name in ‘executeApiCalls’. Here’s a quick fix:

const executeApiCalls = async() => {
  // GET LOCATION INFO
  const locationInfo = await fetchLocationData(LOCATION_ENDPOINT, API_HOST);
  console.log(locationInfo);
}

This should resolve your issue. Remember, when working with async/await, it’s crucial to maintain clear and unique variable names to avoid such conflicts. Also, ensure your API key and endpoint are correctly configured in your environment variables.
