fix-errors

When fixing an unhandled error from the telemetry dashboard, the issue typically contains an error message, a stack trace, hit count, and affected user count. The error manifests at a specific line in the stack trace, but the fix almost never belongs there . Fixing at the crash site (e.g., adding a typeof guard in a revive() function, swallowing the error with a try/catch, or returning a fallback value) only masks the real problem. The invalid data still flows through the system and will cause failures elsewhere. Read each frame in the stack trace from bottom to top. For each frame, understand: The goal is to find the producer of invalid data , not the consumer that crashes on it. Sometimes the stack trace only shows the receiving/consuming side (e.g., an IPC server handler). The sending side is in a different process and not in the stack.
