Arrow json printing error

Error message

Arrow json printing error: {}

What it means

This error is returned when converting query results to JSON via the arrow JSON writer fails. The inner ArrowError is wrapped and displayed after 'Arrow json printing error: '. It means `arrow::json::writer` could not serialize the RecordBatches.

Solutions

1. Inspect the wrapped ArrowError message for the failing column.
2. Validate batch buffer/schema integrity before formatting.
3. Try CSV or pretty output as an alternative rendering path.
4. Pin a consistent arrow version across the workspace.

Example fix

// before
let json = result.format(format::Format::Json)?;
// after
let json = result.format(format::Format::Json)
    .map_err(|e| anyhow!("json export failed: {e}"))?;

fn is_json_arrow_err(e: &format::Error) -> Option<&ArrowError> {
    match e { format::Error::JsonArrow(a) => Some(a), _ => None }
}

match result.format(format::Format::Json) {
    Ok(j) => use_json(j),
    Err(format::Error::JsonArrow(e)) => eprintln!("json write failed: {e}"),
    Err(e) => eprintln!("other format error: {e}"),
}

When it happens

Trigger: Calling the client's format function with Format::Json on batches the arrow JSON writer cannot handle, such as batches with invalid/null buffer layouts.

Common situations: Serializing results containing types unsupported by the installed arrow JSON writer, or data corrupted by an earlier mismatched arrow version.
