angular - Encryption/Decryption Padding error on Linux with JAVA Backend

Question

I′m currently developing on OSX and i use these two classes to decrypt and encrypt messages:

TypeScript (Angular):

export class Crypter{
  
  public static encrypt(value){
    let key = CryptoJS.enc.Utf8.parse(environment.crypterKey);
    let iV = CryptoJS.enc.Utf8.parse(environment.crypterIV);
    let ciphertext = CryptoJS.AES.encrypt(value, key, {
      iv: iV,
      mode: CryptoJS.mode.CBC,
      padding: CryptoJS.pad.Pkcs7
    }).toString();
    return ciphertext;
  }

  public static decrypt(value){
    let key = CryptoJS.enc.Utf8.parse(environment.crypterKey);
    let iV = CryptoJS.enc.Utf8.parse(environment.crypterIV);
    let decryptedData = CryptoJS.AES.decrypt(value, key, {
      iv: iV,
      mode: CryptoJS.mode.CBC,
      padding: CryptoJS.pad.Pkcs7
    });
    return decryptedData.toString( CryptoJS.enc.Utf8 );
  }
}

JAVA:

public class Crypter {

    private final String key = "secret0000000000";
    private final String iV = "0000000000secret";

    public String encrypt(String toEncrypt) {
        try {
            IvParameterSpec iv = new IvParameterSpec(iV.getBytes("UTF-8"));
            SecretKeySpec skeySpec = new SecretKeySpec(key.getBytes("UTF-8"), "AES");
            Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
            cipher.init(Cipher.ENCRYPT_MODE, skeySpec, iv);
            byte[] encrypted = cipher.doFinal(toEncrypt.getBytes());
            return new String(Base64.getEncoder().encode(encrypted));
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }

    public String decrypt(String toDecrypt) {
        try {
            IvParameterSpec iv = new IvParameterSpec(iV.getBytes("UTF-8"));
            SecretKeySpec skeySpec = new SecretKeySpec(key.getBytes("UTF-8"), "AES");
            Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
            cipher.init(Cipher.DECRYPT_MODE, skeySpec, iv);
            byte[] cipherText = cipher.doFinal(Base64.getDecoder().decode(toDecrypt));
            return new String(cipherText);
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }
}

it works while developing on OSX but not on Linux (Raspberry). Couldn't find a working solution so far. I get the following error:

javax.crypto.BadPaddingException: Given final block not properly padded. Such issues can arise if a bad key is used during decryption.
