I am now getting this error on an app that was working prior to 2.3. The app no longer works.

What app? Since you posted in the Rule Machine category, I might assume that, but knowing for sure--plus seeing how your app is set up and knowing what device and driver you're using (the erorr you posted is coming from a device, not an app)--would be good.
