UiPath Error Handling and Debugging Flashcards

Which UiPath activity allows you to add a custom message to the Output panel during debugging without affecting production logs?

Answer: Write Line

Write Line outputs a string to the Output panel in Studio and is commonly used for quick debugging messages during development.

What does the 'Watch' panel in UiPath Studio debugger allow you to do?

Answer: Track specific variable or expression values as the debugger steps through activities

The Watch panel lets you pin specific variables or expressions to monitor their evolving values as you step through execution during debugging.

What is the recommended UiPath approach for handling a 'Selector Not Found' exception in a web automation workflow?

Answer: Use a Try Catch block around the web activity and retry or use an alternative selector

Wrapping selector-dependent activities in Try Catch allows graceful recovery, logging, or fallback logic when an element cannot be found.

In UiPath, what is the 'Exception' variable automatically created in a Catch block?

Answer: A reference to the caught exception object, allowing access to .Message and .StackTrace properties

The Catch block automatically provides an exception variable of the caught type, giving access to properties like Message, StackTrace, and InnerException.

Which UiPath Studio feature lets you temporarily disable an activity without deleting it?

Answer: Disable Activity

Right-clicking an activity and choosing 'Disable Activity' greys it out and excludes it from execution, similar to commenting out code.

What does the 'Execution Trail' feature in UiPath Studio debugger show?

Answer: A visual trace of previously executed activities highlighted in the workflow designer

Execution Trail highlights the sequence of activities that were executed, helping developers trace the path taken through complex conditional workflows.
