Topic: Storing multiple resources at once using Bundle

I'm having some trouble trying to store multiple resources in a single request. If I understand correctly the best way to do this would be using a batch or transaction. Here is some Kotlin code I've been trying with Hapi (both server and client at version 3.8.0). 

val bundle = Bundle()
bundle.type = Bundle.BundleType.BATCH

conditions.forEach { condition ->
    bundle.addEntry()
            .setResource(condition)
            .request
                    .setUrl("Condition")
                    .setMethod(Bundle.HTTPVerb.POST)
}

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

Unfortunately the server is giving me the following error:

HTTP 400 : This is the base URL of FHIR server. Unable to handle this request, as it does not contain a resource type or operation name.

I've tried with Bundle.BundleType.TRANSACTION and with client.transaction().withResources(conditions).execute() as well but both give the same error.

If I don't use my own Hapi server but the one on https://fhirtest.uhn.ca/ it does seem to work. Here I've pasted the generated XML in the "transaction" box on the home page. Is there something I need to configure on my Hapi server to make this work?

you have to use a transaction bundle and send it against the base url of the FHIR server.

client.transaction().withBundle(bundle).execute()would be the correct one for sending a transaction bundle to the server.

Well, this is what I'm doing. This is what I am doing to create the client:

        val context = FhirContext.forR4().restfulClientFactory
        val tokenInterceptor = BearerTokenAuthInterceptor(token)

        client = context.newGenericClient("http://localhost:8080/fhir")
        client.registerInterceptor(tokenInterceptor)

I can see a request to http://localhost:8080/fhir with the bundle as an xml body.
