各位大家好：
紧急求助！
我之前一直用sql-client提交SQL任务，今天突然不能提交了，报错如下：
Exception in thread "main" org.apache.flink.table.client.SqlClientException:
Unexpected exception. This is a bug. Please consider filing an issue.

Shutting down the session...
done.
不知道是哪里出问题了，在yarn上看flink-session任务是正常的，其中的其他任务都正常运行，就是不能提交了。
请求各位大佬帮助。
