Tracking Custom Issues in Web apps

What is CustomIssue in Web apps?

CustomIssue is a flexible telemetry event used to log non-error, non-fatal anomalies or specific analytic states that don't fit the definition of a strict exception.

Why it matters

Sometimes applications enter weird states that aren't technically code crashes, but still indicate a problem. Custom Issues allow product and engineering teams to track the exact state tree when these strange behaviors occur.

Why does this happen?

Analytics State Mismatches

Logging an issue when the internal shopping cart total does not match the Stripe checkout total, even though no code actually crashed.

User Reported Anomalies

Providing a "Report a Bug" button in the UI that explicitly logs a CustomIssue with a screenshot and the user's message attached directly to the session trail.

How to fix it using Appxiom

• Analyze stack trace: Appxiom provides the exact minified and source-mapped stack trace pointing directly to the line of JavaScript/TypeScript code that triggered the issue.
• Trace activity trail: The activity trail provides a chronological list of user interactions (clicks, route changes) and network calls that occurred right before the issue, helping developers reproduce the exact user journey.
