    Receiving a cache.json download error when trying to perform an application cache clear and rebuild per the instructions in KB 19519.


    The contents of the cache.json folder can be read in a Notepad and are as follows (timestamps will be different): 
    {"Timestamp":"2017-01-27T15:44:42","ErrorCode":"HttpUnhandledException","IsLogged":true,"IsUIReady":true,"InternalMessage":null,"Message":"Unhandled system exception: Exception of type 'System.Web.HttpUnhandledException' was thrown.","StackTrace":null,"ExceptionType":null}

    The below is one possible resolution for this situation.

     


    Resolution

    The account running the HEATAppServerAppPool in Internet Information Services (IIS) Manager needs to have full access to the HEATCache folder, and all child folders, located on the Application Server.
