Log downloads NoRegionError.

[decarv]

I am trying to download the logs with cw_utils but I keep getting NoRegionError. Does anyone know how I can I fix this?

stream_name = 'XXXX'
fname = 'logs/deepracer-%s.log' %stream_name
cw_utils.download_log(fname, stream_prefix=stream_name)

I will close this as the problem got fixed.
