If an account is not fully-synced, you may see the following error message:

{
  "error": "Connection(Operation { error: TransactionValidation(ContainsSpentKeyImage), total_delay: 0ns, tries: 1 })"
}

Call check_balance for the account, and note the synced_blocks value. If that value is less than the local_block_height value, then your TXOs may not all be updated to their spent status.
