Solutions

1. Choose a different target type for the field; the primary key type is reserved for the attribute view's block key.
2. If you need a primary key, create a new attribute view or edit the existing primary key field instead.

Example fix

Set the field type to a supported non-primary type such as text, number, date, or select instead of block/primary key.

When it happens

Trigger: Calling /api/av/updateAttributeViewKey (or the database field type menu) attempting to change a field's type to the primary key (block) type.

Common situations: Occurs when the user tries to change an attribute view field's type to the primary key (block) type via the API or the field settings UI; only the existing primary key may hold that type.
