The error codes below can affect the assessment in the following ways:
- Global UI Error - this is a fatal error that will stop the Learnosity app from working and is not recoverable. Users will see an error message printed out on the screen explaining the error. They will have to try loading the assessment again or report the issue.
- Question UI Error - this is a fatal error that only applies to an individual problematic Question instance. Other Question instances are not affected and will continue to work as expected.
- Alert Only - this is a recoverable error where the user can retry their last action before the error occured. For example, failing to save due to no network connectivity.
