In my scenario, I use a REST API to retrieve the account ID by providing the user's email. Then, I pass this account ID to create a project on Jira using RESR API.
The issue is that if I don't provide any email in the field, Jira creates a user named 'System' and generates it as the lead. Sometimes, it's created with an ID like '102085dd---b***-23dc1877****' as the lead ID.
The problem arises when I try to delete or suspend this user. I encountered an error saying 'Cannot remove a system user.' I would like to understand why this is happening.
