How to avoid JsonMappingException "problem: In direct mode, you must specify either the SellOffer or the BuyOffer."

[wandapen]

att;
When I sync block with tx like this code on block 75603952:

UnsignedInteger index = UnsignedInteger.valueOf(blockNumber);
LedgerResult ledgerResult = xrplClient.ledger(LedgerRequestParams.builder() .ledgerSpecifier(LedgerSpecifier.of(LedgerIndex.of(index))).transactions(true).build());
I receive the exception like the title, how to avoid this?

xrpl4j version: 2.5.0
