[SOLVED] cURL on AWS Lambda gives command not found error

Issue

Starting a few hours today, a simple curl command on Lambda is failing.
Lambda environment is NodeJs 10.x (have also tried in 12.x).

const { execSync } = require('child_process');

exports.handler = async (event) => {
   execSync('curl http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/images/BigBuckBunny.jpg -o /tmp/BigBuckBunny.jpg');
    const response = {
        statusCode: 200,
        body: JSON.stringify('Hello from Lambda!'),
    };
    return response;
};

I get a /bin/sh curl: command not found error Any idea what the issue is?

Response:
{
  "errorType": "Error",
  "errorMessage": "Command failed: curl http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/images/BigBuckBunny.jpg -o /tmBigBuckBunny.jpg\n/bin/sh: curl: command not found\n",
  "trace": [
    "Error: Command failed: curl http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/images/BigBuckBunny.jpg -o /tmBigBuckBunny.jpg",
    "/bin/sh: curl: command not found",
    "",
    "    at checkExecSyncError (child_process.js:621:11)",
    "    at execSync (child_process.js:657:15)",
    "    at Runtime.exports.handler (/var/task/index.js:11:4)",
    "    at Runtime.handleOnce (/var/runtime/Runtime.js:66:25)"
  ]
}

Solution

Finally i have a confirmation from Amazon support (and their internal tech team) that CURL binary is no longer included as part of the AWS Lambda environment based on Amazon Linux 2. Which is why I am not able to perform curl using either execSync or spawnSync in Node 10 and Node 12.

The alternative as per them is to use the "requests" library https://github.com/request/request/blob/master/README.md#streaming
