I can not reach the object 'additionalInfoList' by XML from SOAP

[andreaLuongo]

I can not reach the object 'additionalInfoList' by XML from SOAP.

We pass this XML via Postman to ServiceNow, which is able to retrieve all the values via request.key, and we are able to send them as a response to Postman, so the call arrives successfully.

The problem arises when we try to access the additionalInfoList object via code. This object contains several items, which in turn are composed of paramname and paramvalue, which change both in number and value each time.

I tried using code to pass me the value logs via a for loop that accesses the object, but without success.

Below you will find the XML that we pass through Postman, the scripted Web Service code, the log outside the for loop that returns undefined for the number of items contained in the object, and finally the response from the scripted Web Service that returns the first value of the XML routingID, confirming that the XML has been correctly received by ServiceNow.
