Parsing message with ~ character fails.

[richard-mihalovic]

Hi, we have an incoming HL7 message like in this example and we want to get the number 7777 from PID.3.5 segment. But we are not able to get it.

HL7 file:

MSH|^~\&|1.2||||20250126162659||ADT^A03^ADT_A03||P|2.5^FRA^2.5|||||FRA|8859/1|||
PID|||0001^^^MCK&1.2&L^PI~7777^^^ASIP-SANTE-INS-C&1.3&ISO^INS-C^^|

Code:

const hl7Message = hl7Parser.create(message);
const path = 'PID.3.5';
console.log(path, '=', hl7Message.get(path).toRaw());

Output:

PID.3.5 = PI

I suppose the expected output should be: PI~7777.
