DDtKey opened a new issue, #4941:
URL: https://github.com/apache/arrow-datafusion/issues/4941
**Describe the bug**
If there is no valid fields for query it returns an error:
`Schema Error: No field named 'table'.'field'. Valid fields are .`
**To Reproduce**
```rs
let schema = DFSchema::empty();
let err = schema.index_of_column_by_name(Some("t1"), "c0").err().unwrap();
println!("{err}");
```
Or via SQL like this:
```sql
SELECT not_existed;
```
**Expected behavior**
`Valid fields are .` could be misleading, better to avoid this part of
message or replace it
