Hi @alamb Can I try this ?
Should be enough to check if the coerced args in the aggregation returns no
result (in physical_plan/aggregates) ?
```rust
let arg = coerce(args, input_schema, &signature(fun))?;
if arg.len() == 0 {
return Err(DataFusionError::Plan(format!(
"Invalid aggregation '{}'",
name,
)));
}
```
