SyntaxError: Unexpected end of JSON input after getting All-Orders-Access approval

[kevinrt06]

Hi everyone, I'm having some issues since I created a new App to work locally on my original App that is already on Production. Yesterday, I requested access to all orders from my Shopify Partner's Account. When they gave me that access, I ran my App but I'm getting this message:

I already add the same scopes that I have in my Production's App in this new App. The unique difference between both is that the original one has a Public App distribution since we want to publish it in the Shopify App Store, the new one for development purposes is a Custom App distribution, so I don't know if that will be affecting the app to get the error I'm having. 

I'll appreciate any support with this issue.
