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

Confirm srcRowID exists in the AV's block key values before invoking DuplicateAttributeViewRow.

source row [%s] not found in attribute view [%s]

Error message

source row [%s] not found in attribute view [%s]

What it means

Thrown by DuplicateAttributeViewRow when blockKeyValues.GetValue(srcRowID) returns nil, i.e. the row selected for duplication does not have a value in the primary (block) key column. The source row must exist in the AV before it can be copied.

Solutions

Confirm srcRowID exists in the AV's block key values before invoking DuplicateAttributeViewRow.
Refresh the row list on the client when the AV is updated externally (sync, another window) and invalidate cached row IDs.
Surface a user-facing 'row no longer exists' message instead of silently failing.

Example fix

// before
DuplicateAttributeViewRow(tx, avID, prevID, maybeDeletedRowID, newRowID)
// after
rows := attrView.GetBlockKeyValues()
if rows.GetValue(srcRowID) == nil {
  return fmt.Errorf("source row %s no longer exists", srcRowID)
}
DuplicateAttributeViewRow(tx, avID, prevID, srcRowID, newRowID)

Defensive patterns

Strategy: validation

Validate before calling

const blockVals = av.getBlockKeyValues()
const srcExists = blockVals && blockVals.values.some(v => v.blockID === srcRowID)
if (!srcExists) { /* source row is gone; do not call DuplicateAttributeViewRow */ }

Try / catch

try { await duplicateRow(avID, prevID, srcRowID, newRowID) } catch (e) {
  if (/source row .* not found/.test(String(e.message ?? e))) { refreshRows(avID) } else { throw e }
}

Prevention

Invalidate cached row IDs when the AV is modified externally.
Confirm the source row exists immediately before invoking duplicate.

When it happens

Trigger: Passing a srcRowID that was already deleted, belongs to another AV, or was never committed; calling duplicate during a sync that has not yet pulled the row.

Common situations: Stale selection state in the frontend after a delete/sync; programmatic callers reusing a row ID cached from a previous session.
