As indicated in the error message, the specifications only allow one Field 5 "Observed Value" in OBX. If you look at OBX Set Id 31 it has multiple meanings (using a repeating char).

This is prohibited in HL7 v2.2 - but it is allowed in version 2.3.
Thus, you have several options:
- edit the post header to be v2.3
- force the parser to use the 2.3 specs.
Forcing the parser is as easy as
PipeParser parser = new PipeParser();
IMessage hl7Message = parser.Parse(hl7, "2.3");
Duress for HL7 v2.4
PipeParser parser = new PipeParser();
IMessage hl7Message = parser.Parse(hl7, "2.4");
