LEASE_EXPIRED

The lease was older than its validity window when the transaction arrived.

HTTP status	409
Group	Relay path
Retryable	Yes — the same request may be sent again
Re-sign	SAME_BYTES — resend the transaction you already have, byte for byte

What happened

A lease is short-lived on purpose: it is the only freshness bound a MultiversX transaction (which never expires) can be given.

What to do

If details.renewable is true, renew the lease and resend the same signed bytes. Otherwise assign again and sign once more.
