webj3，如何正确调用RevertReasonExtractor.extractRevertReason？

如何解决webj3，如何正确调用RevertReasonExtractor.extractRevertReason？

使用以太坊web3j library，如何获取交易失败的恢复原因？

我需要“启用回复原因呼叫”吗？怎么样？

我应该在data和revertReasonCallEnabled参数中传递什么值？

public call(RemoteFunctionCall call) {
  try {
    call.send();
  } catch (TransactionException e) {  
    System.out.println("revert reason: " + e.getTransactionReceipt.get.getRevertReason()); // returns null 
    String data = ???                   // << what value goes here?
    Boolean revertReasonCallEnabled =   // << what value goes here?
    System.out.println("revert reason extracted: " + RevertReasonExtractor.extractRevertReason(receipt,data,web3j,revertReasonCallEnabled))
  }
}

应该如下吗？

String data = e.getTransactionReceipt.get.getRevertReason()

但是，这将为我的特定远程呼叫返回null；

我已经尝试过使用revertReasonCallEnabled = true和revertReasonCallEnabled = false，但是extractRevertReason总是返回N/A。
