Code Execution Error caused by PowerShell Execution Policy on Windows

[crimson206]

Describe the issue

I intentionally reproduced the test failure of #1759.

#1759 summary : If the execution policy of user's powershell is restricted in window, all the powershell(including .sh) code will cause an error.

I worried that it will stop the application unwantedly.

The expectation was wrong because the code execution process deals with errors by returning error messages,
however it causes another serious problem that we might hate more. See the logs below.

When the execution of some codes are obviously no possible, they keep trying to execute the codes.

It makes me believe that the current code execution process was badly designed.

Steps to reproduce

1. OS : Window
2. Execute the cmd in powershell: Set-ExecutionPolicy Restricted -scope CurrentUser (Why CurrentUser? you might not have the root authority in the current shell).
3. Go to agentchat_auto_feedback_from_code_execution notebook.
4. Replace the message by "Write a simple .sh script in the code block sh ."

To create a simple shell script, we can use the following code:

# My Script

# Print the current date and time
echo "$(date +%Y-%m-%d %H:%M:%S)"

# Print the operating system
echo "$(uname -s)"

# Print a message
echo "Hello, world!"

Explanation:

• The first line, # My Script, is a comment and is ignored by the shell.
• The second line, echo "$(date +%Y-%m-%d %H:%M:%S)", uses the date command to print the current date and time in the format YYYY-MM-DD HH:MM:SS.
• The third line, echo "$(uname -s)", uses the uname command to print the name of the operating system.
• The fourth line, echo "Hello, world!", simply prints a message.

When you run this script in a terminal, it will output the current date and time, as well as the name of the operating system.

Please execute the script by running it in a terminal and let me know if there are any errors or issues.

Solution for PowerShell Security Error in Windows:

If you encounter a security error in PowerShell on Windows with the message:

+ CategoryInfo          : SecurityError: (:) [], PSSecurityException
+ FullyQualifiedErrorId : UnauthorizedAccess

and your execution policy is set to "Undefined," you can resolve it by granting unrestricted execution access to the process scope.

Here's the solution:

1. Open PowerShell as an administrator.

2. Run the following command:

   Set-ExecutionPolicy -Scope Process Unrestricted

   This command sets the execution policy for the current PowerShell session to "Unrestricted," allowing execution access without restrictions.

@crimson206 By following these steps, you authorize access to the code and resolve the security error.
