The JS Errors tab captures uncaught JavaScript errors on your site and groups them so you can prioritise fixes.

Requirements #

• Plan: Opti-Behavior Pro

Steps #

1. Go to Opti-Behavior → Errors Tracking → JS Errors.
2. Review the error table columns: Priority, Error Message, Type, Severity, Occurrences, Sessions, Last Seen, Status.
3. Open an error to see its stack trace and the pages and sessions affected.
4. Filter by severity (Critical, Error, Warning, Info) or status.

Reading priority and severity #

• Occurrences and affected sessions drive how urgent an error is.
• Critical errors block functionality; Info is low impact.

Status workflow #

Move each error through Open → Investigating → Resolved (or Ignored). See the error status workflow.

Expected result #

Errors are grouped, ranked, and traceable to a line of code and a session.

FAQ #

Can I see which visitors hit an error? #

Yes. Each error links to affected sessions; with recordings enabled you can replay them.
