There are NULL user attributes values for your Crowd users in Crowd database.
Workaround
Run the following query in the Crowd Database to identify the exact directories causing the issue:
SELECT * FROM cwd_user_attribute WHERE attribute_value = '' OR attribute_value IS NULL;- Navigate to those directories in
Crowd >> Users >> Attributes, ensure that each of the attributes indeed has a value and save the changes you've made by clickingUpdate.
- Re-attempt the XML export again
