Docker hl7ToJson giving UNKNOWN nodes

I'm new to HL7 and need to do a quick integration with Node so thanks for this package @MatthewVita it's been a lifesaver.
The only issue is when I run docker/examples/hl7ToJson.sh it executes without errors, the JSON result is well formed and I have the MSH segment correct but everything else falls into UNKNOWN under MSH.30
I tried some others examples from the tests dir and the same issue occurs - I can't get it matching the corresponding test .json files. Could it be something to do with new line characters?
I'm on OSX Docker version 20.10.5
Any help would be great thanks
