AsyncGroup.create_dataset() might call AsyncGroup.create_array() without dtype argument #3050
Description
Zarr version
main branch
Description
AsyncGroup.create_array() arguments shape and dtype have no default value, so they are mandatory:
zarr-python/src/zarr/core/group.py
Lines 994 to 1000 in 5ff3fbe
As far as I can see, AsyncGroup.create_dataset() may call AsyncGroup.create_array() without dtype argument if kwargs is missing dtype and data is None:
zarr-python/src/zarr/core/group.py
Lines 1158 to 1160 in 5ff3fbe
Granted, that wouldn't make sense, but it would be better to handle that corner case nicely.
