Workaround

Update the database to provide a default value for the scoped value for Migrate Users task with

update mig_task set scoped = true where tasktype = 'USERS' AND scoped is null;

If you're on Oracle try (capitalisation may be required for table and column name

update mig_task set scoped = 1 where tasktype = 'USERS' AND scoped is null;
