Http Response Parsing JSON string or stream

Hello community,

I am trying to parse the below HttpResponse in Cache. Cannot get the Iterator to work. Is there a single loop which can parse both or single messages and grab the error?

{ txt1:'error msg1'},

{ txt2:'error msg2'},


error: {
'error msg1',

'error msg2'

Cache for Windows (x86-64) 2018.1.1 (Build 312_1_18937U) Fri Apr 26 2019 17:58:36 EDT

I tried dynamic objects but gives me an error, unless i am not doing it correctly or if syntax is not correct.

Set objStream = objHttpResponse.Data
     Set json =""
     While ('objStream.AtEnd) {
          Set json = json _ objStream.ReadLine()

set iter = json.%FromJSON().%GetIterator()
   while iter.%GetNext(.key , .value )
       write "key = "_key_" , value = "_value,!

The issue is the API  is not set up yet on the project which i am working.

But the specs has the JSON PAYLOAD as request and then the response is what i pasted above. 

So i am trying to get the code ready to parse in the meantime until the API is set up. Hopefully i will have something to work with POSTMAN as soon as API is set up.

Once i receive the response , i need to parse it for any error and then shutdown the operation.  At the most i can convert the response to string and check for error.

Yes, this works if you have one level. But what about if you have second level-something like this:

    "statuses": [
        "SW7=ON, SW6=OFF, SW5=OFF, SW4=OFF, SW3=OFF, SW2=OFF, SW1=OFF",
        "Unique Printer ID and Fiscal Memory ID are set",
        "The fiscal memory is formatted"
    "warnings": [],
    "errors": [],
    "ok": true
