JSON Structure Parsing Issue

Question

Question

Saju Abraham · Dec 5

Hello All,

I am facing an issue where the vendor seems to be sending two structures of JSON messages, but only one of them seems to work in my code.
I need help in allowing both the JSON structures to parse into the engine.

Working Example:

{
   "data":
       {
           "idNumbers":
           [
               {
                   "type":"322","number":"123456"
               }
           ]
           ,"0":
           {
               "con_type":"210"
           }
       }
   ,"meta":
   {
       "secret_key":"","origin_url":"cuh.n3.prod-uk.datixcloudiq.co.uk"
   }
}

Not Working:

Context: Extra Square Brackets causing extra arrays and con type sent inside the same array.
Error: Error in the Json/HL7 conversion/transformation block, Origin URL not authorized!
{
   "data":
   [
       {
           "idNumbers":
               [
                   {
                       "type":"322","number":"123456","id":"4155"
                   }
               ]
       },
       {
           "con_type":"210"
       }
   ],
   "meta":
   {
       "secret_key":"","origin_url":"cuhdemo.n3.prod-uk.datixcloudiq.co.uk"
   }
}

My current code:

I need help/suggestions in getting the code modified to accept both the JSON structures.

One thing you could do:
At the top of your BPL, add an <if> checking if "data" is an array or an object:

if context.JsonObjectIn.data.%IsA("%DynamicArray")

If it is, then use an assign to set context.JsonObjectIn.data to the last element of the array (%Pop() returns the last element of an array):

set context.JsonObjectIn.data = context.JsonObjectIn.data.%Pop()

After doing this, the rest of the actions should work the same for either input.

Note that this assumes that when "data" is an array that the array only has one item in it. If it can have multiple items then you'll need to add logic to choose the correct item.
