failed to marshal move request: %w

Error message

failed to marshal move request: %w

What it means

Returned when json.Marshal of MoveRequest fails. MoveRequest consists of strings, a nil-able ContentHash, and passphrase strings — all JSON-safe — so this branch is effectively unreachable with the current type definition.

Solutions

1. Verify the error's %w chain actually points at this Marshal call
2. Keep MoveRequest limited to JSON-encodable scalar fields, or add custom MarshalJSON

if err != nil && strings.Contains(err.Error(), "marshal move request") {
    log.Error("MoveRequest schema defect — not a runtime condition")
}

When it happens

Trigger: Only if MoveRequest gains a channel/func/cyclic field in a fork; nothing in the shipped type can trigger it.

Common situations: Essentially none; treat any occurrence as a sign the error is actually a wrapped child from elsewhere or a modified struct.
