> Does the JS Table reader work?
> I return pa.serialize(pa.Table.from_pandas(df)).to_buffer().to_pybytes() as application/octet-stream from a HTTP endpoint.
> Then using Javascript I try to read it:
> const table = await Table.from(fetch(("/myendpoint")));
>  console.log(table.toString());
> but it prints only [object Object] and using the debugger shows an empty&unusable table. Schema and data is empty, the column with the given name is not found.
> It doesn't throw any error. 
> How is this supposed to work? Do I miss something on the python or JS side?
