HL7v2 Message Not Serializing "\\E\\" EscapeCharacter #7

Open idelfonsog2 opened 2 weeks ago

idelfonsog2 commented 2 weeks ago

We have been using the previous library HL7-dotnetcore and recently moved to the new one HL7-V2. We noticed that messages with "\r" character do not get Serialize. it comes back with different errors:

It seems this issue was fixed in the old library but not in the new one. Please advice what steps to take

jaime-olivares commented 2 weeks ago

Hi Idelfonso, There shouldn't be differences between both libraries. Anyway, we will need some samples for testing.

idelfonsog2 commented 1 week ago

Let me get those,be right back

idelfonsog2 commented 1 week ago

Hi @jaime-olivares So I have the following message below and Im calling:

var strippedMessageStr = message.SerializeMessage(false); 'Failed to serialize the message with error - Index was outside the bounds of the array.'

var strippedMessageStr = message.SerializeMessage(true); Failed to validate the message with error - No Message Found

Hi @jaime-olivares so I identified the issue to be "\E\" in my message

OBX|6|ST|&GDT|1|Internal small hemorrhoids observed during retroflexion\\E\\||||||F||||NMHPOC|NM******^TEST^SAMANTHA^^|||||||||\r

is it the possibility that a practioner might have added the "\" at the end of the line and hence the library is not able to serialize it due to it

jaime-olivares commented 18 hours ago

Sorry, I couldn't find the time to analyze this. Will resume during the weekend.
