Solutions

1. Remove a non-primary field instead; every attribute view requires its primary key field.
2. If the field is unwanted, hide it in the view rather than deleting it.

Example fix

In the database view, use 'Hide' on the primary field, or delete any other field by id.

When it happens

Trigger: Calling /api/av/removeAttributeViewKey or the UI delete-field action on the attribute view's primary key field.

Common situations: Occurs when the user tries to remove the primary key (block) field of an attribute view, either through the table header menu or the batch field-removal API.
