在ClickHouse本机从一张表迁移数据到另一张表，频繁报错Unexpected content at the end of chunk是什么原因？

ClickHouse服务器本机，同一个空间下面，两张表，从A表到B表。每次迁移一会就报错，有人遇到过吗？谢谢。

```
java.sql.SQLException: org.apache.http.MalformedChunkCodingException: Unexpected content at the end of chunk
```

The report names only a local ClickHouse migration from table A to table B and a Java SQLException; it mentions no repository file, test, or entry point. Start by reproducing the migration and collecting the DataX and ClickHouse versions plus the complete error context. Done means identifying a reproducible cause and documenting or fixing it with a regression check.
