> When writing a pandas dataframe to feather using its to_feather method,
> sometimes a single column's conversion fails in pandas_compat.convert_column,
> which leads the whole method to fail. The error message should include the
> name of the column that failed for easier debugging.
>
> Eg instead of:
>
> {code:java}
> ArrowInvalid: Error converting from Python objects to String/UTF8: Got Python
> object of type int but can only handle these types: str, bytes.
>
> {code}
> Throw:
> {code:java}
> ArrowInvalid: Error converting from Python objects to String/UTF8: Got Python
> object of type int but can only handle these types: str, bytes. (column
> "user_id")
> {code}
