Line 107 in 9ef30e0

instance['metadata']['user_data'] = base64.b64decode(instance['metadata']['user_data']).decode('utf-8')

Support many decoding options

Would like support for any decoding of data to support all possible encodings

Version 0.8.0

Backend Server

This is what I did to temporarily get around the issue, I don't think this is a good approach.
