UiPath-ADAv1 Debugging and Exception Handling Practice Question
When dealing with 'SelectorNotFoundException', which THREE actions should a developer consider to increase the robustness of the automation?
⚠ Common exam trap
Candidates often rely solely on hardcoded UI attributes, forgetting that combining dynamic variables, wildcards, and anchors is essential for robust automation.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use dynamic selectors with wildcards for attributes that change frequently.
SelectorNotFoundException is a common challenge in UiPath. Improving selector stability is critical because applications often change their UI structure dynamically. By using reliable attributes, wildcards, and anchors, a developer can ensure the robot remains functional despite minor interface changes, thereby reducing maintenance overhead and improving the overall stability and reliability of the automation solution in production environments.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use dynamic selectors with wildcards for attributes that change frequently.
Why this is correct
Wildcards allow the robot to match UI elements even if parts of their attributes change, such as timestamps or dynamic IDs. This is a best practice for identifying elements in web applications where IDs are generated on the fly, significantly improving the selector's long-term durability.
- ✗
Always increase the 'TimeoutMS' property to a very high value like 300,000.
Why it's wrong here
Setting extremely high timeouts can lead to slow execution and poor performance without solving the root cause of selector instability. Proper timeouts should be based on expected application load times rather than arbitrarily large numbers which hide underlying performance issues in the target application.
- ✓
Use the 'Anchor' feature to identify elements relative to stable UI components.
Why this is correct
Anchors provide a reliable reference point for the robot, ensuring it can find the target element even if the target itself is ambiguous. This is an essential technique for robust automation, especially when dealing with form fields or complex tables that lack unique static selectors.
- ✗
Avoid using 'UiExplorer' as it generates overly complex selectors.
Why it's wrong here
UiExplorer is the recommended tool for identifying stable selectors and testing them. It provides full control over selector attributes and is essential for finding the most robust combination of tags, which is necessary for avoiding SelectorNotFoundExceptions during the execution of complex UI-based automation processes.
- ✓
Use variables in selectors to make them dynamic based on runtime data.
Why this is correct
By injecting variables into selectors, developers can target specific elements based on runtime information, such as row indices or record IDs. This approach makes the automation flexible and able to handle varying datasets, which is crucial for dynamic business processes requiring high precision.
