Dagger Hilt deprecated @ViewModelInject to @HiltViewModel migration issue

recently I migrate the ViewModelInject in dagger hilt to @HiltViewModel by I am getting the error like this.

java.lang.RuntimeException: Cannot create an instance of class io.chativo.chat.viewmodel.TicketViewModel

Original Code

class TicketViewModel @ViewModelInject constructor(
    private val ticketRepository: TicketRepository
): ViewModel() {
.....
}

Updated code

@HiltViewModel
class TicketViewModel @Inject constructor(
    private val ticketRepository: TicketRepository
): ViewModel() {

The original code works perfectly, but after I migrate to @HiltViewModel, I keep getting the Cannot create an instance of class ViewModel error. Any idea why this happen?

build.gradle(app)

apply plugin: 'dagger.hilt.android.plugin'

// dagger - hilt (dependency injection)
implementation 'com.google.dagger:hilt-android:2.31-alpha'
kapt "com.google.dagger:hilt-android-compiler:2.29.1-alpha"
implementation 'androidx.hilt:hilt-lifecycle-viewmodel:1.0.0-alpha03'
kapt 'androidx.hilt:hilt-lifecycle-viewmodel:1.0.0-alpha03'
kapt 'androidx.hilt:hilt-compiler:1.0.0-alpha03'

build.gradle

classpath 'com.google.dagger:hilt-android-gradle-plugin:2.29.1-alpha'

Finally, I get the correct solution by myself. The compiler version should be the same with its library version.

// dagger - hilt (dependency injection)
implementation 'com.google.dagger:hilt-android:2.31-alpha'
kapt "com.google.dagger:hilt-android-compiler:2.31.1-alpha"

Hope this helps someone who struggle for an answer.
