Hey guys,
i hope i am posting this in the correct stream.
I have a problem with sending an ORU message to my hapi fhir jpa server.
I tried the same with the HAPI testpanel and it worked there, but now i installed my "own" server via docker and i get a compiler error.
The port is definitely listening and my firewall shouldn´t make problems. I can access localhost:8080 in my browser.

Does anybody know what "Expected byte '11' in state START but was '72'" means?
Thanks in advance

You might have better luck on chat.hl7.org. This sight generally only deals with v2 in the context of mapping to FHIR.

Haha they sent him here in the first place

But it's very much an HL7 question so I agree with the assessment and think they were wrong
