I think the `RecordBatch` with rows of `1` is as expected, as the input
`some_json` also contains one record (without fields):
```
let some_json: Vec<Result<serde_json::Value, arrow::error::ArrowError>> =
vec![Ok(serde_json::json!({}))];
```
The previous implementation was always giving the error, while the correct
result in this case should be a record batch with a `row_count` of 1. If your
input is `vec![Ok(serde_json::json!({})), Ok(serde_json::json!({})]` the
expected row_count is `2` and with `vec![]` it should give a recordbatch with
`row_count` of `0`.
