attribute view item [%s] not found

Error message

attribute view item [%s] not found

What it means

Before applying a card cover position, the kernel verifies that the row (attribute view item / block value) identified by operation.RowID exists in the parsed attribute view via GetBlockValue. This error means the row ID does not correspond to any existing row in that view.

Solutions

1. Re-fetch the attribute view and confirm the row ID still exists before sending the operation
2. Refresh the frontend view state if the row was deleted by another session
3. Verify AvID and RowID belong to the same attribute view
4. Drop the pending operation if the card was removed — it cannot succeed on retry

Example fix

// before
applyCoverPosition(avID, staleRowID, ...) // row already deleted
// after
const av = await fetchAttrView(avID);
if (!av.blocks.some(b => b.id === rowID)) return refreshView();
applyCoverPosition(avID, rowID, ...)

const rowExists = (av, rowID) => av.blocks.some(b => b.id === rowID);
if (!rowExists(await fetchAttrView(avID), rowID)) return refreshView();

const blockValue = attrView?.blocks?.find?.(b => b.id === rowID);

try {
  await transaction(op);
} catch (e) {
  if (String(e).includes("attribute view item")) {
    await reloadAttributeView(avID); // row deleted concurrently
  }
}

When it happens

Trigger: Calling doSetAttrViewCardCoverPosition with a RowID that was deleted, belongs to a different attribute view, or was never created; also when the AvID and RowID are mismatched after UI state went stale.

Common situations: Concurrent editing where another client deleted the card; stale kanban/gallery state after undo or sync; passing a block ID from a different document; plugin operating on cached row IDs.
