Jefffrey opened a new issue, #8702:
URL: https://github.com/apache/arrow-datafusion/issues/8702

   ### Describe the bug
   
   datafusion-cli isn't showing results for queries involving selecting count 
when group by.
   
   ### To Reproduce
   
   Given input file:
   
   ```csv
   col1,col2
   A,
   B,b
   C,c
   ```
   
   Querying this file in datafusion-cli:
   
   ```
   DataFusion CLI v34.0.0
   ❯ CREATE EXTERNAL TABLE kumachan STORED AS CSV WITH HEADER ROW LOCATION 
'/home/jeffrey/Downloads/kumachan.csv';
   0 rows in set. Query took 0.029 seconds.
   
   ❯ select * from kumachan;
   +------+------+
   | col1 | col2 |
   +------+------+
   | A    |      |
   | B    | b    |
   | C    | c    |
   +------+------+
   3 rows in set. Query took 0.005 seconds.
   
   ❯ select count(*) from kumachan group by col1;
   3 rows in set. Query took 0.010 seconds.
   
   ❯
   ```
   
   ### Expected behavior
   
   Should get results like:
   
   ```
   +----------+
   | COUNT(*) |
   +----------+
   | 1        |
   | 1        |
   | 1        |
   +----------+
   ```
