Using this code:

It ringcentral.http.api_exception.ApiException: Unknown error

I was thinking this may be related to the Python version I was using 3.7 so I switched to 3.6 no joy (What version(s) of Python does it work with BTW?) I'm at a standstill here, any ideas?

from ringcentral import SDK

#sdk = SDK(CLIENT_ID, CLIENT_SECRET, SERVER)

platform = sdk.platform()

platform.login(user, extension, password) #this throws unknown error

builder = sdk.create_multipart_builder()

builder.set_body({

'from': {'phoneNumber': '15551212'},

'to': [{'phoneNumber': '15551213'}],

'text': 'message'

})

request = builder.request('/account/~/extension/~/sms')

response = platform.send_request(request)
