请求我发送：

{"transactionid":"12",
    "ISOMsg":"010046552063310518890000000000000123001203210541330012003255399022004655206331051889=0325111123400008050206305000014291100011001001840"
}

和iam使用packger87解包iso消息：

for (Map.Entry<Object, Object> entry : attributes.entrySet()) {
        if (entry.getKey().equals("ISOMsg")) {
          msg.setPackager(new ISO87BPackager());
          msg.unpack(ISOUtil.hex2byte(entry.getValue().toString()));
        }
      }

错误：

"message": "org.jpos.iso.IFB_LLCHAR: Problem unpacking field 34 (java.lang.RuntimeException: Required 10 but just got 8 bytes) unpacking field=34, consumed=67"

问题出在打包机上？但是我用的是87，MTI0100是87的版本。。提前谢谢
