I was trying to edit a user role (System -> Permission -> User Roles) on the magento 2.3.1 admin panel and I started to get this error:

[2019-06-17 08:34:01] main.CRITICAL: Item (Magento\User\Model\User\Interceptor) with the same ID "11" already exists. [] []
[2019-06-17 08:34:01] main.CRITICAL: The "adminhtml.user.editroles" block threw an exception, and it can't be rendered. [] []

I've tried to google the issue and I've seen similar errors relating to products, however, nothing to do with user roles.

The result of this error is that I see a mostly blank page with no ability to edit the assets that a role has access to.

Appreciate any help.

  • Can you please check your admin_users table by any chance, data with same Id exist. because this issue comes when we tried to modify entity with id which are duplicate. – nishu Jun 17 at 9:00
  • @nishu I've checked this and confirmed that there are no duplicate user_id's – kn04 Jun 18 at 9:19
