error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt

i found the solution. I need to use a permanent secret key that doesn't change

const crypto = require("crypto");const algorithm = "aes-128-cbc";const salt = "foobar";const hash = crypto.createHash("sha1");hash.update(salt);// `hash.digest()` returns a Buffer by default when no encoding is givenlet key = hash.digest().slice(0, 16);crypto.createHash('sha256').update(String(secretkey)).digest('base64').substr(0, 32);const iv = crypto.randomBytes(16);exports.encrypt= function (text) {    let cipher = crypto.createCipheriv(algorithm, key, iv);  let encrypted = cipher.update(text);  encrypted = Buffer.concat([encrypted, cipher.final()]);  return { iv: iv.toString("hex"), encryptedData: encrypted.toString('hex') };}exports.decrypt = function (text) {  let iv = Buffer.from(text.iv, 'hex');  let encryptedText = Buffer.from(text.encryptedData, 'hex');    let decipher = crypto.createDecipheriv(algorithm, key, iv);  let decrypted = decipher.update(encryptedText);  decrypted = Buffer.concat([decrypted, decipher.final()]);    return decrypted.toString();}
