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"

So I have been working in Healthcare Interops for about a month now and in IRIS. I am looking to implement SMART on FHIR and I am currently working to make an endpoint that works as the discovery endpoint. It is a custom dispatch class and unauthenticated is selected for access. I am trying to make a simple get request from Postman to test that the proper JSON is sent, but I receive a 403 Forbidden error. It is reaching IRIS it seems so I know its not a reverse proxy error. Here is an example of my custom Dispatch Class.
