Start with the test_es_sync_utility failure and trace the transaction lookup through lbry/wallet/ledger.py, especially update_history and request_synced_transactions. Read the logged blockchain.transaction.get_batch response and lbry/wallet/network.py handling to determine how a None transaction result reaches the sync utility. Done means the failing lookup no longer raises the reported TypeError and the test passes.
