AFEventFrameSearch serach element at element level and recursively

Hello!

Using latest AF SDK "PI Server 2018" version, trying to find event frames at element level. The need is to look for event frames at the element level and optionally also recursively for all elements under the selected element.

What I tried below is not working, any comments on how to achieve this?

 

Trying to do the same with AFEventFrameSearch

tokens.Add(new AFSearchToken(AFSearchFilter.Target, AFSearchOperator.Equal, context.Element.GetPath()));

Printing of search shows it as : search: SortOrder:Desc Start:>="2019-01-30T15:47:32.1211531Z" End:<="2019-03-01T15:47:32.1481544Z" Root:"\\SRV\PROD_CM\Customers\DemoCustomer\DemoSite\UNIT1" AllDescendants:true

 

However

search.FindEventFrames(startIndex, fullLoad: true, pageSize: limit + 1);is resulting into following error

System.FormatException: The object for '\\SRV\PROD_CM\Customers\DemoCustomer\DemoSite\UNIT1' in search criteria 'Root:"\\SRV\PROD_CM\Customers\DemoCustomer\DemoSite\UNIT1"' was not found.

   at OSIsoft.AF.Search.AFSearch.ResolveObjectPath[T](AFSearch search, AFIdentity identity, AFSearchToken token, String path, Boolean throwOnError, Boolean systemLevel)

 

Thanks,

Jagan
