Code Review

This pull request correctly fixes an issue in searchFhirResourcesGet.js by explicitly setting the responseType to json in the client.request call. This ensures the response from the Healthcare API is properly parsed as JSON, preventing potential errors when accessing the response data. While reviewing this change, I noticed that healthcare/fhir/searchFhirResourcesPost.js contains similar logic but also appears to be missing the responseType: 'json' parameter. It would be beneficial to apply a similar fix to that file to ensure consistent and correct behavior for both GET and POST search methods.
