>                 Key: ARROW-17256
>                 URL: https://issues.apache.org/jira/browse/ARROW-17256
>             Project: Apache Arrow
>          Issue Type: Bug
>          Components: Python
>         Environment: pyarrow 8.0.0
> python 3.9
>            Reporter: &res
>            Priority: Minor
>
> When calling:
> {code:java}
> pa.chunked_array([], type=pa.bool_()).combine_chunks(){code}
> I get this error:
> {code:java}
>  pyarrow/table.pxi:700: in pyarrow.lib.ChunkedArray.combine_chunks
>     ???
> pyarrow/array.pxi:2868: in pyarrow.lib.concat_arrays
>     ???
> pyarrow/error.pxi:144: in pyarrow.lib.pyarrow_internal_check_status
>     ???
> pyarrow/error.pxi:100: in pyarrow.lib.check_status
>     ???
> E   pyarrow.lib.ArrowInvalid: Must pass at least one array{code}
> While this works:
> {code:java}
> pa.chunked_array([pa.array([], pa.bool_())], type=pa.bool_()) {code}
> In the first case, it should return an empty BoolArray as well.
