[5.x]: User is not authorized to perform this action

[mariuswestgaard]

What happened?

Description

The user I'm signed in with is Admin. But, I'm unable to remove a nested entry in a matrix field. I can update the content in the selected nested entry. The matrix can add max 1 entry. The entry type selected in the matrix is updateable after creating, but I can't remove the nested element. Whenever I click remove in the options for the field, I get the following error even though my user is Admin: User is not authorized to perform this action

Trace:

Steps to reproduce

1. Login to the cms as an admin account.
2. Add a matrix field to a sections entry type, and allow it to add max 1 entry type.
3. Add the entry type to the matrix field in the entry, and save. It worked saving.
4. Try to remove the nested entry type.
5. It fails with the errors described.

Expected behavior

I would expect that the nested were deleted, and I could then add a new nested entry.

Actual behavior

I can't delete the nested entry.

Hi, thanks for getting in touch! I’m not able to reproduce this.
What view mode is this matrix field using? Could you also please turn on the safeMode and see if you’re still getting the same behaviour?
