The python-xarray autopkgtest is failing on s390x, because the arch is
big-endian and so the lookup for the dtype in from_numpy fails;
zarr/core/metadata/v3.py only lists in dtype_to_data_type, for
example, "<i8" and not ">i8".
I think the solution to this is simply to add the equivalent
big-endian dtypes to this dict.
I'll do a team upload with this change later today, as this is causing
a lot of potential autorms.
Best wishes,

AFAIK the version of zarr v3 currently in debian does not support BE
architectures.
Support for BE will be probably available in Zarr v3.1 (not an option
for trixie).
It is not clear to me what kind of patch you want to propose for zarr,
but a common workaround for the client code (xarray in this case) is to
force the numpy "in-memory" representation to LE before storing it into
zarr.
Kind regards
