Uncaught (in promise) API does not exist

I’m trying to add existing backend to a new react frontend. Every time I call the API from react i get, Uncaught (in promise) API api3ceaf69c does not exist

Client side code

function getData() {
  const apiName = "api3ceaf69c"; 
  const path = "/users"; 
  const myInit = {
    
    headers: {}, 
  };
  return API.get(apiName, path, myInit);
}

(async function () {
  const response = await getData();
  console.log(JSON.stringify(response));
})();

index.js

import { Amplify, API } from "aws-amplify";
import awsExports from "./aws-exports";
Amplify.configure(awsExports);
API.configure(awsExports);

aws-exports.json

{
    "aws_cloud_logic_custom": [
            {
                "name": "api3ceaf69c",
                "endpoint": "https://xxxxxxx.execute-api.ap-south-1.amazonaws.com/dev",
                "region": "ap-south-1"
            }
        ]
}

“aws-amplify”: “^4.3.27”

I went through multiple answers around the same issue but none of them are working for me.

Interestingly this exact same code was working a few days back until I had to rebuild my backend due to some changes.

Answer

I figured out the problem finally! Issue was at the place where I’m calling Amplify.configure(aws_exports). For some reason aws exports was not getting initialized in index.js file so I moved it closer to where I am actually calling the api, i.e. getData() function. It started working post that.
