> When I run this:
> {code:java}
> mt_array <- Array$create(mtcars)
> write_to_raw(mt_array){code}
> I get this error:
> {code:java}
>  Error: schema must be a "Schema" {code}
> We should add a manual check of the type of the input that returns a more informative error message if the object is not a data.frame, RecordBatch or Table
