What is your issue?

Using xr.open_dataset to read .nc files that I am looping through. The loop works for for first 20 or so files and then I get the error "ValueError: buffer size must be a multiple of element size". I already have a check to see if the .nc is an empty file and I am opening the file with "dataset = xr.open_dataset(fsspec.open(filename).open(), chunks={})"

sample code:
xr.set_options(file_cache_maxsize=10)
for gcm_folder in GCM_files:
filename = glob.glob('ClimateProjections/LOCA/LOCA2_downloads/' + gcm_folder + '/*')[0]
if os.path.getsize(filename) == 0:
print(gcm_folder, 'is an empty file')
continue
dataset = xr.open_dataset(fsspec.open(filename).open(), chunks={})
