Flink1.15.1读取Tidb6，sql-client执行select count异常 java.sql.SQLSyntaxErrorException

Hi，
环境：
flink-1.15.1
TiDB-v6.1.0


现象：
Flink SQL> select count(*) from t1;

[ERROR] Could not execute SQL statement. Reason:

java.sql.SQLSyntaxErrorException: You have an error in your SQL syntax; check 
the manual that corresponds to your TiDB version for the right syntax to use 
line 1 column 12 near "FROM `origin_object_data_61`" 

执行失败了


Flink SQL> select * from t1 limit 3;
执行成功了，有结果返回


请教下各位，为什么count不能执行，select字段就可以执行？？


Thanks
