Encountering an issue with async/await in RapidAPI request

Other Questions RapidAPI

I'm having trouble with a RapidAPI GET request. When I 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 GEO_URL = "https://location-finder.example.com/ip/verify?format=json";
const GEO_HOST = "location-finder.example.com";

const fetchData = async(url, host) => {
  const result = await fetch(url, {
    method: "GET",
    headers: {
      accept: "application/json",
      "x-example-host": host,
      "x-example-key": API_KEY
    }
  })

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

  return await result.json();
}

const executeQueries = async() => {
  const fetchData = await fetchData(GEO_URL, GEO_HOST);
  console.log(fetchData);
}

executeQueries();

What am I doing wrong? How can I fix this error?

looks like u’ve got a naming conflict. ur fetchData function has the same name as the const inside executeQueries. try renaming one of em, maybe call the function getApiData() or smthn. that should fix the ‘cannot access before initialization’ error ur seeing.

I encountered a similar issue recently when working on a project. The problem stems from variable shadowing - you’re using ‘fetchData’ as both a function name and a variable name within the same scope. This confuses JavaScript’s lexical scoping rules.

To resolve this, I’d suggest renaming the function to something more descriptive, like ‘fetchLocationData’. This not only fixes the error but also makes your code more self-documenting. Here’s how I’d modify the executeQueries function:

const executeQueries = async() => {
  const locationData = await fetchLocationData(GEO_URL, GEO_HOST);
  console.log(locationData);
}

Remember to update all references to the function throughout your codebase. This approach maintains clean, unambiguous code and prevents similar issues in the future.

The error occurs because you are using the same name, fetchData, for both your function and the variable inside executeQueries. In JavaScript, this leads to a naming conflict, resulting in the ‘Cannot access before initialization’ error. To fix the issue, rename either your function or your variable. For example, you could rename your function to fetchApiData as shown below:

const fetchApiData = async(url, host) => {
  // ... existing function code ...
}

const executeQueries = async() => {
  const data = await fetchApiData(GEO_URL, GEO_HOST);
  console.log(data);
}

This should resolve the error and let your code run as intended.
