I was trying to initialize a spatialdata object directly from S3 as done in the tests here:

from upath import UPath
import spatialdata as sd
test = UPath( "s3://spatialdata/spatialdata-sandbox/merfish.zarr", endpoint_url="https://s3.embl.de", anon=True )
sd.read_zarr(test)

Was failing with:

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
Cell In[1], line 4
      2 import spatialdata as sd
      3 test = UPath( "s3://spatialdata/spatialdata-sandbox/merfish.zarr", endpoint_url="https://s3.embl.de/", anon=True )
----> 4 sd.read_zarr(test)

File ~/src/spatialdata/_io/io_zarr.py:282, in read_zarr(store, selection, on_bad_files)
    272     attrs = None
    274 sdata = SpatialData(
    275     images=images,
    276     labels=labels,
   (...)    
    281 )
--> 282 sdata.path = _create_upath(_store)
    283 return sdata

File ~/src/spatialdata/_core/spatialdata.py:590, in SpatialData.path(self, value)
    588     self._path = value
    589 else:
--> 590     raise TypeError("Path must be `None`, a `str` or a `Path` object.")
    592 if not self.is_self_contained():
    593     logger.info(
    594         "The SpatialData object is not self-contained "
    595         "(i.e. it contains some elements that are Dask-backed "
    596         "from locations outside {self.path})."
    597     )

TypeError: Path must be `None`, a `str` or a `Path` object.

The implemented changes fix the issues and result in the sdata object being successfully read from S3.

The code now returns:

I can take a look to see if I can figure out the problem.
