I have installed marketing Cloud Fuel SDK using the instructions from Github(https://github.com/salesforce-marketingcloud/FuelSDK-Python.)
I set up the environment variables:
os.environ['FUELSDK_CLIENT_ID']
os.environ['FUELSDK_CLIENT_SECRET']
os.environ['FUELSDK_ACCOUNT_ID']
os.environ['FUELSDK_AUTH_URL']
os.environ['FUELSDK_BASE_API_URL']
os.environ['FUELSDK_DEFAULT_WSDL']
os.environ['FUELSDK_SOAP_ENDPOINT']

When I run my python code, i keep getting this error:

Unable to validate App Keys(ClientID/ClientSecret) provided: {'error': 'unsupported_grant_type', 'error_description': 'Use "authorization_code" or "refresh_token" or "client_credentials" or "urn:ietf:params:oauth:grant-type:jwt-bearer" as the grant_type.', 

Any idea what i could be doing wrong?

The Error I get is: "Step Not yet complete... here's what's wrong: 
Please check that your report includes at least all of these columns: Supply: Supply Name, Unit Cost, Quantity and Total. 
Note: you may run into errors if you've skipped previous steps."
this is my report:

not sure where I made a mistake

I am trying to set up email2Case Agentand getting this error. 
Tried almost everything but couldnt 
I will appreciate any help.
