Internal Server Error at Root Route /

[ericBlack1]

Description:
Accessing the root route / triggers an internal server error (HTTP 500) due to an intentional exception in the code.

Steps to Reproduce:

1. Run the Flask application using the provided code snippet.
2. Open a web browser and navigate to http://127.0.0.1:5000/.
3. Observe the error message and stack trace in the browser or console.

Expected Behavior:
The root route / should display the message "Welcome to your first Flask application!" or handle the exception gracefully.

Actual Behavior:
An internal server error (HTTP 500) occurs, with the following error message:

Internal Server Error: /  
Traceback (most recent call last):  
  File "<file_path>", line <line_number>, in home  
    raise Exception("Internal server error.")  
Exception: Internal server error.  

Code Snippet:

from flask import Flask

app = Flask(__name__)

@app.route('/')
def home():
    raise Exception("Internal server error.")
    return "Welcome to your first Flask application!"

if __name__ == '__main__':
    app.run(debug=True)

Development Environment:

• OS: Ubuntu 24.04.
• Python Version: 3.12.3
• Flask Version: 3.0.3

Suggested Fix:
Handle the exception gracefully or remove the exception to ensure the route works as expected. Example fix:

@app.route('/')
def home():
    try:
        # Logic here
        return "Welcome to your first Flask application!"
    except Exception as e:
        return f"An error occurred: {str(e)}", 500
