Sample repro to aid in debugging for issue: microsoft/azure-health-data-services-toolkit#140
To reproduce the stream issue, open the HealthToolkit.sln and run it using the docker-compose profile.
Next, run the HealthToolkit api and copy the URL of the API.
Then, open the ClientApp.sln and paste the URL in the Program.cs at the fhirServelUrl variable.
The ClientApp will attempt to send requests to the FHIR API in a loop as it seems this i the easiest way to have the error occur.
Note: The FHIR request itself will end up in a 404, but this is intentional as the actual issue occurs before the binding is executing the actual http call.
Run the ConsoleApp and check the API project logs. You should see some requests fail with the below error.
