Text Survey Error Handling

The new survey app designer handles invalid input automatically. The default action is to repeat the node up till the max retry time.

Extra Message for error

In the Error Handling Options section, you can specify additional message to send when an error occurs. You can also define the max retry time.

If additional message is specified for error handling, then it is sent 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.
