Databinding seems a bit tricky to do with Kotlin. Is there a reason you are making the errorText nullable? Your code seems fine and should work. You can try making it a non nullable type and try again. If that does not work, try casting the viewmodel.error to a String in the layout

<com.google.android.material.textfield.TextInputLayout
                       android:id="@+id/pin_edit_text_layout"
                       android:layout_width="match_parent"
                       android:layout_height="wrap_content"
                       app:errorEnabled="true"
 app:errorTextAppearance="@style/ThemeOverlay.MaterialComponents.TextInputEditText.OutlinedBox"
                       app:errorText="@{(String) viewModel.error}>

what is the type for viewModel.error ? is it LiveData<String>?

ObservableField<String>
