UiPath Certification UiPath Error Handling and Debugging

Question 1

Which UiPath activity is used to catch and handle exceptions during workflow execution?

Accepted Answer

Try Catch

Answer

The Try Catch activity wraps risky code in a Try block and routes caught exceptions to matching Catch handlers or a Finally block.

Question 2

What is the purpose of the 'Throw' activity in UiPath?

Accepted Answer

Intentionally raises an exception to signal an error condition

Answer

The Throw activity programmatically raises a specified exception type, allowing workflows to signal error conditions explicitly.

Question 3

In UiPath debugging, what does a 'Breakpoint' do?

Accepted Answer

Pauses execution at a specific activity so you can inspect variable values

Answer

Breakpoints pause workflow execution just before the marked activity, allowing the developer to inspect the current state in the Locals panel.

Question 4

Which UiPath debugging feature allows you to execute the workflow one activity at a time?

Accepted Answer

Step Into

Answer

Step Into (F11) executes one activity at a time and enters invoked workflows to trace each nested step.

Question 5

What is the difference between 'Rethrow' and 'Throw' activities in UiPath?

Accepted Answer

Rethrow re-raises the currently caught exception preserving its stack trace; Throw raises a new exception

Answer

Rethrow is used inside a Catch block to re-raise the same caught exception with its original stack trace intact, while Throw creates a new exception.
