Use of FHIRPath.API not returning results as expected

I have been struggling sometime with trying to take a FHIR Bundle Response, extract the "entry.resourceType", extract the MRN and Name from the Patient FHIR Response...

Going through learning.intersystems.com, it suggested that I try using fhirPathAPI to parse and search my response for certain values, however I am not sure my syntax is correct. Using the AI code, it suggested to set my tree = "Bundle.entry.resource.resourceType"

ClassMethod Transform(source As HS.FHIRServer.Interop.Response, target As osuwmc.Epic.FHIR.DataStructures.PatientSearch.Record) As %Status
{
  Set tSC=$$$OK
  set tQuickStream = ##Class(HS.SDA3.QuickStream).%OpenId(source.QuickStreamId)
  set tRawJSON = ##Class(%Library.DynamicObject).%FromJSON(tQuickStream)
  set fhirVersion = $lb("hl7.fhir.r4.core@4.0.1")
  set fhirPathAPI = ##class(HS.FHIRPath.API).getInstance(fhirVersion)
  set tree = fhirPathAPI.parse("Bundle.entry.resource.resourceType")
  do fhirPathAPI.evaluate(tRawJSON, tree, .OUTPUT)
  $$$TRACE("FHIRResponseToPatient Transform: FHIR resource type: "_OUTPUT)
  return tSC
}

however, nothing is returned, but I do see it within the raw JSON that there is an Entry within the Bundle message...

set tree = fhirPathAPI.parse("Bundle.total")

I can get the total number of records returned. 

How do I get the entry level tree, then iterate through identity and name to get the values I need? I seem not to be able to find any examples or clear documentation on how to handle FHIR responses if you are not hosting the repository but getting data from one.
