c# - TestCaseData attribute does not match when TestCaseData has function call

Question

In the following code, GetTestCaseData is not able to map to ProcessFilterRecords_ReturnsData(). The test explorer does show the yield return value but the debugger never enters ProcessFilterRecords_ReturnsData(). If I pass string directly to JArray.Parse(), that works.

public class SampleClass
{
  private static IEnumerable<TestCaseData> GeTestCaseData
  {
    get
    {
         yield return new TestCaseData("arg1val1", JArray.Parse(JsonConvert.SerializeObject(GenerateList(4))));
         yield return new TestCaseData("arg1val2", JArray.Parse(JsonConvert.SerializeObject(GenerateList(5))));
    }
  }

  [TestCaseSource(typeof(SampleClass), "GeTestCaseData_List")]
  public void ProcessFilterRecords_ReturnsData(string arg1, JArray testdata)
  {
    //Arrange 

    //Act

    //Assert
    Assert.IsTrue(true);
  }

  public static GenerateList(int n)
  {
    var data = new List<int>();
    for(int i=0;i<n;i++)
    {
        data.Add(i);
    }
    return data;    
  }
}
