Issue in AES encryption for android - dev vs release build using react-native-crypto-js package

import CryptoJS from "react-native-crypto-js";

//encryption function used in react native code base

export const encryptValue = (text) => {

try {

        const key = 'J4f9eO8ayjjEtamRBxSSmsDqXBele1zl'
        const iv = CryptoJS.lib.WordArray.random(128 / 8)
        let encrypted = CryptoJS.AES.encrypt(
            text, key, {
                keySize: 16,
                iv: iv,
            });
        let v = { iv: iv.toString(), encryptedData: encrypted.toString() }
        return v
    } catch (error) {
        console.log('error - ', error)
    }
}

const crypto = require('crypto-js')

//decryption function used in server - node

export const decrypt = (data) => {


try {

        let key = "J4f9eO8ayjjEtamRBxSSmsDqXBele1zl"
        let decrypted = crypto.AES.decrypt(
            data.encryptedData, key, {
                keySize: 16,
                iv: data.iv
            }).toString(crypto.enc.Utf8)
        console.log('decrypted - ', decrypted)
        return decrypted.toString()
    } catch (err) {
        console.log('err', err)
    }

}

Above code encryption and decryption works fine for android debug build and server side code. However, Android build generated in release.. generates encrypted text, but does not decrypt at server.
