HAPI-0287: This is the base URL of FHIR server... on Transaction Bundle Request

[Timothée Baguet]

Hi,

I'm using HAPI FHIR 5.7.2 with R4 context.
I've setup a simple Fhir Restful Server with a ResourceProvider for AuditEvents

I'm trying to send a transaction Bundle to this server to create multiple AuditEvents

To do so i've set up a simple IGenericClient

String auditServerRootUri = new StringBuilder()

.append("https://")

.append(serverProperties.getHost())

.append(":")

.append(serverProperties.getPort())

.append("/fhir")

.toString();

client = ctx.newRestfulGenericClient(auditServerRootUri); Then i create a transaction bundle with an AuditEvent and i sent it to the server 

public void testFhir(AuditEvent event) {

Bundle bundle = new Bundle();

bundle.setType(Bundle.BundleType.TRANSACTION);

bundle.addEntry()

.setResource(event)

.getRequest()

.setUrl("AuditEvent")

.setMethod(Bundle.HTTPVerb.POST);

client.transaction().withBundle(bundle).execute();

}

But the response i get from the server is a FHIR error : 
HAPI-0287: This is the base URL of FHIR server. Unable to handle this request, as it does not contain a resource type or operation name. And this is weird because if i understood correctly, Bundles are supposed to be send to the server base URI so it shouldn't be an issue +  the request does in fact contains a resource type : "resourceType":"Bundle" I've ran out of ideas so if anyone has any idea i'm all ears tanks !

You need to define a provider to actually handle the FHIR transaction operation- Just having a resource provider to deal with AuditEvent resources doesn't do it, since HAPI's plain server doesn't/can't know anything about how transaction semantics work on your server.

There's an example here: https://hapifhir.io/hapi-fhir/docs/server_plain/rest_operations.html#system_transaction - Note that you need to put this in a plain provider (ie not a provider implementing IResourceProvider) since it's a system level interaction.

Cheers,

James
