Hi, I am having the same issue with the ionic2-starter-aws. I tried the solution offered here, using the aws-mobile-hub aws-sdk.min.js instead of the one with the starter kit, but it did not help. I also tried creating a new app, but had the same problem.
Like Hairus, I only have this problem when trying to view or add a Task. The auth process works fine.
I am running ionic 3.
This is my error message,
CredentialsError: Missing credentials in config
Stack trace:

Thank you for your help!
