What is fallback Task group in vDesigner2.0?
3 Likes
The Fallback Task Group feature in vDesigner 2.0 enhances error handling by providing an alternative execution path when a task fails. It ensures continuity in workflows and allows developers to define custom error-handling logic using system-defined or user-defined exceptions.
When to Use
Use the Fallback Task Group when you want to:
- Prevent workflow breakdown due to runtime errors.
- Gracefully recover from API failures, transformation errors, or invalid inputs.
- Redirect execution to an alternative flow without manual intervention.
Common Use Cases
- API Upload Failures: Redirect to a fallback group if the upload API fails after a media capture task.
- Validation-Based Branching: Route logic based on user-defined validation errors like age or data constraints.
- Network Failure: Switch to offline-compatible flows when the internet is unavailable.
The task group defines what happens when the user performs a certain action. The Fallback task group is like a normal task group that we create for the application to execute generic tasks or actions relevant to the application.
