error: [Hilt] Null baseElement: java.lang.NullPointerException: Null baseElement

Question

I am trying to use Hilt to write some UI instrumented test.

I followed instructions given at developer site to setup Hilt for tests. But when i try running the test, i get following error -

Task :app:kaptDebugAndroidTestKotlin FAILED
e: error: [Hilt]

  [Hilt] Processing did not complete. See error above for details.

FAILURE: Build failed with an exception.

I have setup a CustomTestRunner class -

class CustomTestRunner : AndroidJUnitRunner() {

override fun newApplication(
    cl: ClassLoader?,
    className: String?,
    context: Context?
): Application {
    return super.newApplication(cl, HiltTestApplication::class.java.name, context)
}

}

And replaced default testRunner with this class.

Then i setup my test as follows -

@HiltAndroidTest
@RunWith(AndroidJUnit4::class)
class MyFragmentTest {

    @get:Rule var activityScenarioRule = ActivityScenarioRule(TestActivity::class.java)

    @get:Rule var hiltRule = HiltAndroidRule(this)

    @Before
    fun setup() {
        hiltRule.inject()
    }

    @Inject
    lateinit var testPropertiesManager: TestPropertiesManager


//UI test

Any ideas what could be the issue here?
