The error ERR_CACHE_MISS in MIT App Inventor usually shows up when a WebViewer or Chrome tries to reload a page and the cache data isn’t handled properly, when any web page demands the browser to re-enter some data or reload the data on view. It occurs when the resources within the cache have problems that will not let it work properly. It comes as a notice that asks the user to do something like enter any form data that must be filled in again or reload the page to repair the problem.

Some fixes that can be tried are as follows:-

  1. Clear your browser/app cache and cookies.
  2. In WebViewer settings, disable caching if possible.
  3. Make sure you’re on the latest version of Chrome or MIT App Inventor companion.
  4. Use in-app navigation instead of the browser’s back button.

In short, this error comes from cached data, not from MIT App itself, so clearing or disabling cache normally solves it. Hope it helps!
