Parameter count mismatch in unit test uwp project

I've a UWP project for which I'm doing unit testing. Here's the code

[UITestMethod]
[DataRow("123", IMAdSize.Banner300x50)]
public void TestValidCreationOfIMBannerObject(string placementId, IMAdSize size) {
    IMBanner banner = new IMBanner(placementId, size);
    List<IMErrorCode> receivedEvents = new List<IMErrorCode>();

    banner.OnAdFailed += delegate (object sender, IMErrorCode e) {
        receivedEvents.Add(e);
    };

     Assert.AreEqual(receivedEvents.Count, 0);
}

However, when I run the above test case, I get exception as below:

System.Reflection.TargetParameterCountException: Parameter count mismatch

I am sending both the parameters that are required by the test case, cannot figure out what could possibly be wrong with above code.

I am encountering the same issue: It seems that DataRow and UITestMethod together cause this error, as switching to TestMethod gets rid of the error.
