In this guide, we will cover all the ways to fix the issue along with the probable causes of the problem. Let’s start!

What causes the Try-Catch not working issue in PowerShell?

There could be various reasons why the statement is not working on PowerShell. Here are some of the most common ones: 

Default ErrorAction set – If the ErrorAction is set to Continue, then Try-Catch will not work as expected.  Syntax errors – If the syntax used is improper, the formatting is incorrect, or it is missing keywords, Try-Catch will not work. Cmdlet or function behavior – Some functions and cmdlets come with their error-handling behavior, which might not be compatible with Try-Catch. Incorrect logic or use of variables – If there is an inappropriate use of variables or incorrect logic, then Try-Catch will not work. 

What can I do if the Try-Catch is not working on PowerShell?

1. Check Syntax

Try {# code to run here}Catch {# error handling code here}

2. Check if you are trapping a specific error 

You need to verify if you are trapping specific errors you want to handle and not all the errors. Follow these steps to do the same:

3. Set ErrorAction value 

The default value for ErrorAction is Continue; however, for Try-Catch to work, you need to set the ErrorAction value to Stop. To do this, follow these steps: Try {Get-ChildItem -Path C:\DoesNotExist -ErrorAction Stop}Catch {Write-Output $_.Exception.Message}

4. Use the correct exception type

It is important to use correct exceptions when using Try-Catch, as it can only handle exceptions of the System.Exception type. If you have used non-System.Exception errors, then Try-Catch will not work. As for non-System.Exception, you need to use the NET” framework’s error handling mechanism or catch the error.

5. Avoid script termination 

If your script is terminated before reaching the Catch block, Try-Cach will not get a chance to handle the error. To avoid script termination, follow these steps: Try {Get-ChildItem -Path C:\DoesNotExist}Catch {Write-Output $_.Exception.MessageContinue}

6. Use the Try-Catch-Finally

 If the Try-Catch statement is still not working, you can use the Try-Catch-Finally construct instead. This ensures that your code runs to completion, even if an exception is raised. Try {# Your code here} Catch [System.Exception] {# Exception handling code here} Finally { # Clean-up code here} So, these are ways in which you can resolve the Try Catch not working issue on PowerShell.
