[Bug] Fix Scanner Crash: "Cannot access 'totalScans' before initialization" and missing renderFamilyTree function

[omprakash-sahu-code]

Problem

While trying to scan a URL, the application crashes and shows some JavaScript ReferenceErrors. Because of this, the scan does not complete and an error message appears on the screen.

Expected vs Actual Behavior

Expected: The URL should be scanned successfully, the dashboard stats should update, and the Typosquatting Family Tree should be displayed.

Actual: The scan fails and shows "Scan Error: An unexpected error occurred" "Error: Cannot access 'totalScans' before initialization". When checking the browser console, multiple JavaScript errors can be seen.

Steps to Reproduce

Method 1: Using the Deployed Application

1. Open the deployed Cybershield application in a browser.
2. Enter any valid URL (for example: https://github.com/Mrinalray/Cybershield_URL) in the input field.
3. Click on Scan URL.
4. Observe the error message displayed on the page.
5. Open the browser developer tools (F12) and check the console for errors.

Method 2: Using a Local Development Environment

1. Clone the repository and set up the project locally.
2. Run the application and open it in a browser.
3. Enter any valid URL in the scanner input field.
4. Click on Scan URL.
5. Observe the error message displayed on the page.
6. Open the browser developer tools (F12) and check the console for errors.

Current Behavior

The following errors appear:

1. ``

   • The script crashes during initialization because it tries to access a DOM element (#teamGrid) that is not available.
   • Due to this, variables like totalScans are not initialized properly.

2. ``

   • The code calls renderFamilyTree(data.typosquatting) while displaying Typosquatting results.
   • However, the function does not seem to be defined, which stops further execution.

Expected Behavior

• URL scanning should work without crashing.
• Dashboard statistics such as "URLs Scanned" and "Threats Blocked" should update correctly.

Environment

• Browser: Chrome / Edge
• OS: Windows
• Device: Desktop

Hi @Mrinalray ,

I would like to work on this issue under GSSoC 2026.

I have reviewed the issue description and understand the reported problems involving the initialization error (Cannot access 'totalScans' before initialization), DOM element access issues, and the missing renderFamilyTree() function. I can investigate the root cause, implement a proper fix, and thoroughly test the URL scanning workflow to ensure dashboard statistics and typosquatting visualization work correctly.

Kindly assign this issue to me under GSSoC 2026.

Thank you!
