Survey app error handling
The new survey app designer handles common errors (wrong input or no input) automatically. The default action is to repeat the node up till the max retry time.
Extra audio message for errors
In the Error Handling Options section, you can specify additional audio file to play when an error occurs. You can also define the max retry time.
If an audio file is specified for error handling, then the audio file is played before the node is retried.
Node Specified Error Handling
The generic error handling applies to all nodes. This is normally enough for most applications. If you would like to handle errors differently, you can add conditions in the node itself. For example, the following figure shows how to simply exit the survey if an answer is invalid.
