To prevent this issue, you can remove the email associated with the
Cancel step from the Workflow.
The other option is to add an email address to the system user in the Database. To do so,
1- Run this query on the Database:
select * from users where username='system'
2- Confirm that there is no email address under the email column in the Database.
3- Add a valid email address to the system user by running
update users set email='name@company.com' where username='system'
4- Re-run select * from users where username='system' to confirm that the system user now has an email address associated with it
5- Complete the Autoerrors: the cancellation will be successful
