      Workaround

      Perform the workaround in the instance that has the problematic data in it.

      1. Identify the problem record with the below SQL: 
        select * from customfield where cfname is null or cfname = '';
      2. Navigate to Administration > Custom Field and find the empty name custom field.
      3. Rename the field with at least one non white space character
      4. Attempt a reindex.
