Unable to RSA decrypt in PHP openssl

[swaranbm]

Decryption using PHP Openssl 1.1.1w fails for a Cipher encrypted using hybrid-crypto-js v4.2.0.
I have verified that the key pair matches.
Is there anything else I am missing here? Kindly help.

JavaScript:

const publicKey = "returned from php reading public_key.pem";
const plainText = "plain text here";
var crypt = new Crypt();
var encryptedText = crypt.encrypt(publicKey, plainText);
// send JSON.parse(encryptedText).cipher to php

PHP:

$privateKey = file_get_contents("./private_key.pem");
$ret = openssl_private_decrypt(base64_decode($_GET['encrypted_text']), $decryptedText, $privateKey);
if (!$ret) echo "decryption failed";
else echo "Decrypted Text: " . ($decryptedText);
