You may encounter an "Missing expression value" error when creating a filter for users who have no value for a specific attribute in a Bulk Task Definition. This article provides instructions on how to correctly configure these filters to return results where attributes are empty.
To return users who have no value for a specific attribute, you must use a "not equal to" wildcard configuration in your filter expression. Follow these steps:
Navigate to your Bulk Task Population Object Filter configuration.
Locate the filter expression field.
Configure the filter to return users where the attribute value does not equal *. Use the following syntax example: where ( [Attribute Name] != * )
Note: Replace [Attribute Name] with the actual attribute you are filtering.
