[BUG] : Content Script Fails to Load Due to Duplicate const Declarations in triggerBlogGeneration

[VarshithReddy2006]

Description

While reviewing the browser extension content script, I found that triggerBlogGeneration() declares the variables difficultyElement and difficulty twice within the same block scope using const.

Because const declarations are block-scoped and cannot be redeclared within the same scope, the browser throws a parse-time SyntaxError before the content script can load.

As a result, the extension's page monitoring and blog generation workflow become completely non-functional.

Code Evidence

First declaration:

const difficultyElement = document.querySelector('.difficulty') ||
    document.querySelector('.text-difficuly-easy') ||
    document.querySelector('.text-difficuly-medium') ||
    document.querySelector('.text-difficuly-hard');

const difficulty = difficultyElement
    ? difficultyElement.innerText.trim()
    : "Unknown Difficulty";

Later in the same try block:

const difficultyElement = document.querySelector('[class*="difficulty"]') ||
    document.querySelector('[class*="Difficulty"]');

const difficulty = difficultyElement
    ? difficultyElement.innerText.trim()
    : "Unknown";

Location

extension/content.js

Steps to Reproduce

1. Load the extension in Chrome using Load unpacked.
2. Open the Extensions page and inspect the extension.
3. Observe the content script initialization.
4. The browser fails to parse the script.

Actual Behavior

The content script fails during parsing with an error similar to:

SyntaxError: Identifier 'difficultyElement' has already been declared

or

SyntaxError: Identifier 'difficulty' has already been declared

The script never loads.

Expected Behavior

The content script should parse successfully and execute normally so that problem data extraction and blog generation can function.

Impact

• Content script does not load.
• Blog generation workflow becomes unavailable.
• Page monitoring and data extraction fail entirely.
• Extension functionality is effectively broken.

Suggested Fix

Remove the duplicate declarations or reuse the existing variables instead of redeclaring them within the same scope.

Severity

Critical

Confidence

High — verified through direct source code inspection.

Hi @vanshaggarwal27 ,

I verified and reproduced this issue through source code inspection. The content script contains duplicate const declarations within the same block scope, which results in a parse-time SyntaxError and prevents the extension from loading.

I have identified the root cause and would be happy to work on a fix and submit a PR.

Could you please assign this issue to me?

Thank you!
