Common error downloading across several datasets

I receive an error trying to download some variables of CERRA single level reanalysis using CDS toolbox using the suggested toolbox request. For example, the following request for "2m_temperature":

import cdstoolbox as ct
@ct.application(title='Download data')
@ct.output.download()
def download_application():
    data = ct.catalogue.retrieve(
        'reanalysis-cerra-single-levels',
        {
            'variable': '2m_temperature',
            'level_type': 'surface_or_atmosphere',
            'data_type': 'reanalysis',
            'product_type': 'analysis',
            'year': '2020',
            'month': '01',
            'day': '01',
            'time': '00:00',
        }
    )
    return data

Returns the following error:

The above exception was the direct cause of the following exception:

The same error is returned when trying to download '10m_wind_speed', except it includes in the error message:

ValueError: Can't convert 'm s**-1' to '1'.

Downloading 'snow_depth', and 'surface_pressure' had also failed. However, the suggested toolbox request does work for some other variables (eg. tested on 'medium_cloud_cover' and 'liquid_volumetric_soil_moisture'). 

The error message suggests that there is an error in converting the units, however my code does not call for unit conversion. It seems like something on the client side (i.e., request handler for the dataset). Concerningly, the the same error message has been reported using when downloading UERRA - Access to wind direction, however, their request does work for me as of 2023-08-14. 

The issue may also be related to this post for ERA-5 variables, however I do not know how to obtain the request request based on the Request ID (0ee966ba-5a47-42a9-acde-0265378f2185).
