SharePoint 2013, "Call web service" action to "UpdateListItems" I'm passing this to update a list item in another web:
<?xml version="1.0" encoding="utf-8"?>
<m:listName>OIG IT Support Ticket Tracking</m:listName>
<Batch PreCalc='TRUE' OnError='Continue'>
<Method ID='1' Cmd='Update'>
It works great almost all the time; however, for some records it returns this error:
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<ErrorText>The user does not exist or is not unique.</ErrorText>
<z:row ows_...loads of awesome data... />
As far as I can tell, any user in a Created By, Modified By, or "People Picker" type field in the target record is a current, valid user, and often the same users that appear in other non-problem records.
Intuition says this is probably some SharePoint problem and nothing to do with Nintex, but maybe someone else has run into this?
I suppose I should add that we just (over the weekend) upgraded from 2010 to 2013; however, I'm finding indications that this has been happening for several months.
Any help would be appreciated.
