CPI xpath not working for xml prefixes

[i_elsayed]

I'm trying to use generateNextPersonID in the CPI to get the next person's ID .

1- response :

<?xml version="1.0" encoding="utf-8" standalone="yes"?><d:GenerateNextPersonIDResponse m:type="SFOData.GenerateNextPersonIDResponse" xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"><d:personID>4405</d:personID></d:GenerateNextPersonIDResponse>

2- I defined 2 namespace in the runtime configuration

3- I defined content modifier step to get the personID value but  it's blank

i tried the below xpaths

xpath : /d:GenerateNextPersonIDResponse/d:personID

XPath: //d:personID

result :
