alamb opened a new issue, #12833:
URL: https://github.com/apache/datafusion/issues/12833
### Describe the bug
In certain rare cases, Min/Max queries on string columns like this
```sql
SELECT b, max(a) FROM fuzz_table GROUP BY b
```
Will error like
InvalidArgumentError("number of columns(1) must match number of fields(2) in
schema"
https://github.com/apache/datafusion/pull/12667
### To Reproduce
Uncomment tests from the aggregation fuzzer
```
// ArrowError(InvalidArgumentError("number of columns(1) must
match number of fields(2) in schema"))
// .add_sql("SELECT b, max(a) FROM fuzz_table GROUP BY b")
// .add_sql("SELECT b, min(a) FROM fuzz_table GROUP BY b")
```
### Expected behavior
Tests should pass
