What causes "attribute view item [%s] not found" in siyuan-note/siyuan?

Re-fetch the current rows and re-select a valid startItemID before pasting

attribute view item [ ] not found

Error message

attribute view item [%s] not found

What it means

After validating count, getAttributeViewPasteRowsFromTable scans table.Rows for the row whose ID equals startItemID to use as the paste anchor. If no row matches (start remains -1), the anchor item no longer exists in this table and this error is returned.

Solutions

Re-fetch the current rows and re-select a valid startItemID before pasting
Check the row still exists (matching row.ID) before issuing the paste request
Fall back to appending at the end of the table when the anchor cannot be found, if product logic allows

Example fix

// before
const startItemID = staleSelection.rowID
// after
if (!table.Rows.some(r => r.id === staleSelection.rowID)) { return fallbackAppendAtEnd() }
const startItemID = staleSelection.rowID

Defensive patterns

Strategy: validation

Validate before calling

const anchor = table.rows.find(r => r.id === startItemID)
if (!anchor) { throw new Error(`anchor row ${startItemID} no longer exists`) }

Try / catch

rows, err := getAttributeViewPasteRowsFromTable(table, startItemID, count)
if err != nil && strings.Contains(err.Error(), "attribute view item [") {
    rows, err = appendAtTableEnd(table, pastedData) // fallback
}

Prevention

Re-read current rows immediately before pasting instead of using stale selections
Handle concurrent edits that delete the anchor row
Scope startItemID to the same group being queried

When it happens

Trigger: Calling GetAttributeViewPasteRows with a startItemID that was deleted, or that belongs to a different view/group than the one being searched.

Common situations: Concurrent editing removed the anchor row between UI interaction and API call; startItemID taken from a stale selection; anchoring on a row in another group of a grouped view.
