At the current time, i have an issue with test InsertTestCase.test_insert(self) (InsertTestCase in tests.sql.test_insert):

self = <clickhouse_sqlalchemy.drivers.native.connector.Cursor object at 0x0000024F900F7250>
operation = "INSERT INTO t (x) VALUES ('test')", seq_of_parameters = [{}]
context = <clickhouse_sqlalchemy.drivers.native.base.ClickHouseExecutionContext object at 0x0000024F900F7790>

    def executemany(self, operation, seq_of_parameters, context=None):
        self._reset_state()
        self._begin_query()
    
        try:
            execute, execute_kwargs = self._prepare(context)
    
            response = execute(
                operation, params=seq_of_parameters, **execute_kwargs
            )
    
        except DriverError as orig:
>           raise DatabaseException(orig)
E           clickhouse_sqlalchemy.exceptions.DatabaseException: Orig exception: Code: 102. Unexpected packet from server localhost:9000 (expected Data, Exception, Log or TableColumns, got Progress)

clickhouse_sqlalchemy\drivers\native\connector.py:175: DatabaseException

Can you reproduce it in your branch?
