os: rh9.2 iotdb 2.0.5 use table

Describe the bug and provide the minimal reproduce step

create pipe DA
with source (
'database-name'='nezha',
'mode.snapshot'='false',
'mode.streaming'='true',
'inclusion'='data.insert,data.delete',
)
with sink (
'sink'='iotdb-thrift-sink',
'node-urls' = '127.0.0.1:6669', -- 目标端 IoTDB 中 DataNode 节点的数据服务端口的 url
'username'='root',
'password'='xxxxxxxxxxx'
);

当我删除数据的时候pipe会直接报错并进入状态 stop

What did you expect to see?

Data is synchronizing normally

What did you see instead?

pipe error
