@InjectMocks EncryptDecryptUtil edUtil = new EncryptDecryptUtil();

@Mock
SecretKeySpec secretKey;

@Test
void setSaltKeyTest() {
    setSaltKey("anyKey");
}

@Test
void setSaltKeyTest_Exception() {
    Assertions.assertThrows(NullPointerException.class, () -> {
        setSaltKey(null);

    });
    String s = new String();

    try {
        Mockito.when(s.getBytes(Mockito.anyString())).thenThrow(UnsupportedEncodingException.class);
        Assertions.assertThrows(UnsupportedEncodingException.class, () -> {
            setSaltKey("");

        });
    } catch (UnsupportedEncodingException e) {
    }

}

@Autowired
SystemPropertyRepository systPropertyRepo;

@Test
void encryptByAESTest() throws UnsupportedEncodingException {
    String s = new String("Hello");

    try {
        Mockito.when(s.getBytes(Mockito.anyString())).thenThrow(UnsupportedEncodingException.class);
        Assertions.assertThrows(UnsupportedEncodingException.class, () -> {
            edUtil.encryptByAES("hi");
        });
        
        Mockito.when(systPropertyRepo.findSystemPropertyByName(Mockito.anyString())).thenReturn(getSystemProperty());
        edUtil.encryptByAES("hi");
    } catch (UnsupportedEncodingException e) {
    }

    

}

private SystemProperty getSystemProperty() {
    SystemProperty prop = new SystemProperty();
    prop.setName("any");
    prop.setValue("any");
    return prop;
}

}

I am getting org.mockito.exceptions.misusing.InvalidUseOfMatchersException: Misplaced or misused argument matcher detected

There are a lot of articles on this error around but none of them worked for me. Is there any issue with Mockito.anyInt() because Mockito.anyString() is being used in the previous line and that works fine. Any help is appreciated.
