Mobilefirst 7.1 Adapter - CLI

Question

I am using MobileFirst CLI 7.1. I am following the tutorial ( https://developer.ibm.com/mobilefirstplatform/documentation/getting-started-7-1/foundation/hello-world/integrating-mfpf-sdk-in-cordova-applications/ ) and almost everything works fine. I am using the RSSAdapter and I keep getting the following error when I deploy the app to the phone:

status  :   500

    responseHeaders     {5}

This is how my code looks like:

Update: in recent iFixes, the default adapter was changed to no longer point to CNN. If you haven't, please upgrade.

There is nothing wrong with your project. For whatever reason it appears that the default adapter created has stopped working with the CNN website; it is being investigated.

In the meanwhile you can either use an adapter from a different project (that is working with the engadget website), or create your own.

See for example the adapter that is provided as part of the Starter Application sample (you can copy the adapter folder to your MobileFirst project and use "mfp push" to deploy it to the server; make sure to update the adapter and procedure names in your applicative code).
