Getting familiar with Einstein Vision by doing the tutorial at https://metamind.readme.io/v1/docs

Everything fine until I try to predict against the demo image and I just get:

{"message":"Forbidden!"}

That's no fun. I've checked & refreshed my token; the modelid is correct; I can access the sample image...

Anyone have insight on the specific meaning of this message?

Hello,

I have this error when I try to check challenge:

Challenge Not yet complete... here's what's wrong: 
Could not find an account named 'Blackbeards Grog Emporium' created from Workbench with the Description 'The finest grog in the seven seas.'

In the next picture you can see what I send by the Workbench



The result is succes and in my Developer Org I can see the Account created correctly, but the challenge isn't passed.
