Integrity constraint violation: 1062

when trying to add 1ST user to ZULU got this:

“SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry ‘rob-1’ for key ‘username_UNIQUE’”

besides zulu, a similar error or exact same happen when trying to make other changes using user manager. so it is not just a zulu issue.

the issue seemed to be caused by same login name for multiple users.

the fix here anyway was to make sure there were no duplicate user login names.
