✅ ERROR FIXED + FEATURE CONFIRMATION

Console Error Fixed

❌ Error Was: 

content.js:148 ❌ Analysis error: TypeError: propaganda.techniques.join is not a function

✅ Fix Applied:

Added Array.isArray() checks before calling .join() on:

  • propaganda.techniques
  • linguistic.patterns
  • pretrained.named_entities

Why it happened: Backend might return strings instead of arrays sometimes, or data might be undefined.

How it's fixed: Now checks if it's an array before calling .join(), otherwise displays as-is:

${Array.isArray(propaganda.techniques) ? propaganda.techniques.join(', ') : propaganda.techniques}
