I'm working on a skill and I was trying to add in Isp. It wasn't working so I decided to test it with the github example shown here. https://github.com/alexa/skill-sample-nodejs-fact-in-skill-purchases/blob/master/README.md. That is not working either. I can't seem to get access to the isp api details and it keeps saying failed to load products. I see that the isp products that I made are in my config file but I can't seem to get it to work. Thank you in advance.
