After errors are reported, you can view Issues in the Error Tracking module. In RUM, an Issue is a group of similar errors, typically related to the same bug.
Issue List
For detailed grouping rules, please refer to Error Grouping.

Issue Information Overview

Issue Information Overview
Each entry listed in the Issue browser contains the following information:
ItemDescription
Error type and error messageCore identifying information of the Issue
File path where error occurredLocate error source
Service nameAssociated service
Error causeSystem-inferred possible root cause
Whether issue has regressedIndicates if a resolved issue has reappeared
First and last occurrence timeIssue lifecycle information
Occurrence count chartTrend over time
Occurrence count in selected time periodStatistical data

Issue Status

Issues have 4 statuses, with transitions as follows:
Issue Status Transitions
StatusDescription
For ReviewNewly discovered issues that need attention
ReviewedConfirmed issues being fixed
ResolvedIssues that have been fixed
IgnoredIssues that don’t need handling
For regression-related transition logic, please refer to Issue Status.

Filtering and Sorting

The timeline in the upper right corner of the browser allows you to display Issues that had errors during the selected time period. You can:
  • Select a preset range from the dropdown menu
  • Directly modify the time
  • Enter natural language for filtering

Error Cause Classification

Flashcat adds an error cause classification to each Issue when created, helping improve fault localization efficiency.
Error CauseDescription
Code ErrorErrors caused by code defects
Illegal Object AccessCode accessed a null or undefined object
Invalid ParameterFunction called with invalid parameters
Network ErrorServer response too slow or poor network speed
API Request FailedAPI endpoint returned an error status code
Unknown ErrorUnable to locate this error type
When hovering over an error cause classification, the system will use AI capabilities to provide inferred root causes and fix suggestions.

Regression

Regression refers to previously fixed bugs reappearing.
Regression
If an error is marked as resolved but the same error occurs later (with a different version), the Issue status will be reopened from the closed state and marked as “Regression”.

Issue Details

Click any Issue to open the details panel and view more information.
Issue Details
The top of the panel displays basic Issue information, such as status and error cause. You can also understand the Issue lifecycle: first and last occurrence dates, duration, and error occurrence count over time (aggregated by time granularity).
In the label distribution section, you can view the proportion of different labels under this Issue across various dimensions, quickly determining the impact scope and helping locate root causes.Currently supports labels like view_name, browser_name, version, env, etc.
By default, displays the most recent error information reported during the Issue’s occurrence as an error sample. You can also switch through the navigation bar.
View error context and stack information. If source code has been uploaded, you can see the stack information when the error occurred.
Error Stack
You can view uploaded source code information in “Application Management” - “Source Code Management”. See Source Mapping for details.
View the total number of Session events for the current error sample, as well as user resource access and operations before and after the error occurred.
Currently displays up to 20 context items including the current Error event. You can view more log information in the Session Viewer module later.
Error events carry a series of attributes when reported. You can view current Session, view, user, and other information in the attributes section to help troubleshoot issues.

Best Practices

Configure Source Mapping

Facilitates problem localization in production environments

Add User Information

Configure user-related information to provide better error context

Set Alert Policies

Configure appropriate channels and escalation rules for errors

Regular Error Analysis

Regularly check error reports to discover potential issues

Team Collaboration

Use team ownership features to ensure issues are quickly assigned to relevant teams

Monitor Regressions

Closely monitor potential regressions of resolved issues
