原因

There are NULL user attributes values for your Crowd users in Crowd database.

回避策

  • 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 clicking Update
  • Re-attempt the XML export again
