How do I add Immunization to an FHIR Transaction Bundle? - hl7-fhir

Question

I have downloaded some DSTU2 patient bundles from https://syntheticmass.mitre.org/download.html. I am trying to upload the data to an FHIR test server. My code (using fhir-net-api) loops through several files and compils them into a single transaction bundle. I've included the segment of code below that builds the transaction bundle below.
The problem is that the immunization entries do not have fullUrl element. I thought I was missing a step in in my loop, but according to https://www.hl7.org/fhir/immunization.html, the immunization entry doesn't even support a fullUrl element.
If I build a custom patient with just a few demographic details the process works, so I am guessing that I need to make some alteration to the Immunization entries but I cannot find an example transaction bundle that includes immunization data.
public Bundle ParseTestData(List<string> list) //File data as string in list
{
var parser = new FhirJsonParser();
var parsedBundles = new List<Bundle>();
var transactionBundle = new Bundle()
{
Id = "test-data-bundle",
Type = Bundle.BundleType.Transaction
};
foreach (var str in list)
{
try
{
Bundle bundle = parser.Parse<Bundle>(str);
parsedBundles.Add(bundle);
}
catch (Exception e){/*cut for brevity*/}
}
foreach (var bundle in parsedBundles)
{
foreach (var entry in bundle.Entry)
{
entry.Request = new Bundle.RequestComponent
{
Method = Bundle.HTTPVerb.POST,
Url = "urn:uuid:" + Guid.NewGuid().ToString()
};
transactionBundle.Entry.Add(entry);
}
}
return transactionBundle;
}
My struggle here isn't the c# code. I simply don't know how to structure this data in the bundle properly.
Here is a bit of JSON from the source file.
{
"fullUrl": "urn:uuid:05374078-2d51-4c7e-a562-273b030ba019",

fullUrl lives in the Bundle resource, not in Immunization. Bundles have an array of "entry" elements. Each "entry" (for a transaction request) then contains a "fullUrl", a "resource" and a "request" element. The content for the Immunization goes inside the "resource" element. You can see an example here: http://build.fhir.org/bundle-transaction.json.html. (Just stick your immunization content where the Patient content is.)
