如何下載 Aurora MySQL binlog 到本地伺服器？

需求：需要從 binlog 中獲取指定更新行為的具體細節，這個會是長期需求。

RDS 引擎為 Aurora MySQL ，查閱文檔： (https://docs.aws.amazon.com/zh_tw/AmazonRDS/latest/UserGuide/USER_LogAccess.MySQL.Binarylog.html)

操作步驟： 1.在 EC2 上安裝 mysql 8.0.35 客戶端，連接 RDS 獲取結果：

mysql> select version();
+-----------+
| version() |
+-----------+
| 8.0.28    |
+-----------+
1 row in set (0.00 sec)

mysql> SHOW BINARY LOGS;
+----------------------------+-----------+-----------+
| Log_name                   | File_size | Encrypted |
+----------------------------+-----------+-----------+
| mysql-bin-changelog.000178 | 134217798 | No        |
| mysql-bin-changelog.000179 | 134218106 | No        |
| mysql-bin-changelog.000180 | 134217828 | No        |
| mysql-bin-changelog.000181 | 134217876 | No        |
| mysql-bin-changelog.000182 | 134218108 | No        |
| mysql-bin-changelog.000183 | 134217855 | No        |
| mysql-bin-changelog.000184 | 134217899 | No        |
| mysql-bin-changelog.000185 | 134218171 | No        |
| mysql-bin-changelog.000186 | 134218287 | No        |
| mysql-bin-changelog.000187 | 134217919 | No        |
| mysql-bin-changelog.000188 | 134217812 | No        |
| mysql-bin-changelog.000189 | 134218197 | No        |
| mysql-bin-changelog.000190 |  82797180 | No        |
+----------------------------+-----------+-----------+
13 rows in set (0.01 sec)

2.在 EC2 上執行命令：

/usr/local/mysql/bin/mysqlbinlog \
    --read-from-remote-server \
    --host=${RdsHost} \
    --port=${RdsPort}  \
    --user ${RdsUser} \
    --password ${RdsPass} \
    --raw \
    --verbose \
    --result-file=/tmp/ \
    mysql-bin-changelog.000179

報錯提示：

ERROR: Got error reading packet from server: Could not find first log file name in binary log index file

請問如何解決？
