I'm using he OSS FHIR Server and tried posting a Bundle containing a Practioner, Patient and QuestionnaireResponse. The Bundle itself posted to Cosmos but was not parsed, the individual resources were not created.
I read somethng about posting to "root", still didn't work.
Not sure if i'm missing something
Quoting the FHIR Wiki:
In short if you post your bundle to server.root.url/Bundle the bundle will be stored 'as is' without being processed, whereas if you post to server.root.url then the bundle will be processed as expected, creating contained resources.
