canal无法从rds oss读取binlog

canal版本：1.1.1 数据库版本：rds mysql5.7

ak信息是我自己子账号生成的，账号有管理rds和oss权限，数据库实例是昨天建的，我想从开始binlog拉，启动后一直报错

2019-04-25 10:52:02.934 [destination = example , address = rm-xxxxxx.mysql.rds.aliyuncs.com/172.xx.xx.xxx:3306 , EventParser] ERROR c.a.o.c.p.inbound.mysql.rds.RdsBinlogEventParserProxy - dump address rm-xxxxxx.mysql.rds.aliyuncs.com/172.xx.xx.xxx:3306 has an error, retrying. caused by java.io.IOException: Received error packet: errno = 1236, sqlstate = HY000 errmsg = Could not find first log file name in binary log index file at com.alibaba.otter.canal.parse.inbound.mysql.dbsync.DirectLogFetcher.fetch(DirectLogFetcher.java:102) ~[canal.parse-1.1.1.jar:na] at com.alibaba.otter.canal.parse.inbound.mysql.MysqlConnection.dump(MysqlConnection.java:216) ~[canal.parse-1.1.1.jar:na] at com.alibaba.otter.canal.parse.inbound.AbstractEventParser$3.run(AbstractEventParser.java:252) ~[canal.parse-1.1.1.jar:na] at java.lang.Thread.run(Thread.java:748) [na:1.8.0_191]

配置如下 canal.instance.mysql.slaveId= 14321
