Here is the reproduction script I used to verify this:
```rust
use arrow_json::ReaderBuilder;
use arrow_schema::{DataType, Field, Schema};
use std::sync::Arc;
use std::io::Cursor;
fn main() {
let schema = Arc::new(Schema::new(vec![
Field::new("a", DataType::Int32, true),
]));
let json = r#"{"a": "not_an_int"}"#;
let cursor = Cursor::new(json);
let reader = ReaderBuilder::new(schema).build(cursor);
match reader {
Ok(mut reader) => {
let result = reader.next();
match result {
Some(Err(e)) => println!("Found expected error: {}", e),
Some(Ok(batch)) => {
println!("Batch read successfully (unexpected): {:?}",
batch);
}
None => println!("No batch read"),
}
}
Err(e) => println!("Error building reader: {}", e),
}
}
```
Output:
```
Found expected error: Json error: whilst decoding field 'a': failed to parse
"not_an_int" as Int32
```
