Can't regrid dataset

[jbadag]

Hi,
I am trying to regrid a netcdf file downloaded from https://smn-ar-wrf.s3-us-west-2.amazonaws.com/index.html#DATA/WRF/DET/2023/10/28/00/. Specifically, I am attempting to regrid the file WRFDETAR_01H_20231028_00_001.nc to a rectangular coordinate system in a region bounded by (-60º, -48º) in longitude and (-36, -25º) in latitude. To do this, I wrote the following Python code:

import xarray as xr
import numpy as np
import xesmf as xe

ds = xr.open_dataset('WRFDETAR_01H_20231028_00_001.nc', decode_coords = 'all', engine = 'netcdf4')

lon_new = np.arange(-60, -47.9, 0.1)
lat_new = np.arange(-36, -24.9, 0.1)

regridder = xe.Regridder(ds, {'lon': lon_new, 'lat': lat_new}, method='bilinear')
ds_out = regridder(ds)

However, when I run it, I get an error message (attached a screenshot). Does anyone know why this is happening?

Hi @jbadag, I wasn't able to reproduce your bug, this code works on my side...

Would you be able to update xESMF and try again ?

For reference, I am using xESMF 0.8.2. And my xr.show_versions() gives:
