Error Report

Error report lets you view up-to-the-minute Lua system errors and warnings for both server and client. Monitor your error report before and after updating your experience to identify potential issues early.

Viewing Your Error Report

To view your experience's error report:

  • Navigate to your Creations page in the Creator Dashboard and select your experience.
  • Select Error Report.

You can view analytics for individual or group owned experience. To view the latter, you need to have group permissions for analytics.

Monitoring Errors and Warnings

You can apply the following filters and toggles to your error report:

  • Date range: Filter to last 1 hour, last 1 day, last 7 days, or last 30 days.
  • Place: Filter by place.
  • Show version: Adds place version annotations to the errors and warnings chart. Use this to search for errors and warnings by keyword.
  • Severity: Filter to show errors, warnings, or both.

Below the filters and toggles, a chart displays the numbers of errors and warnings for server, client, and total. Use this chart to look for increases in errors and warnings over time. If you see a large spike in errors and warnings, use the error report table to troubleshoot.

Errors and warnings shown over time by category.

Troubleshooting Errors and Warnings

The Errors and Warnings table has the following columns:

CountNumber of errors or warnings.

MessageError or warning message.
The error report table.

Viewing the stack trace for an error or warning

If you see a dropdown on an error or warning, click to expand it and see its corresponding stack trace. A stack trace is a list of the calls that your experience was performing when the exception was thrown. This can help you figure out what's going wrong.

Error and Warning limits

The error report can report up to 500 unique errors and 500 unique warnings at a time. The report drops any unique warnings after this limit and resets every 6 hours. To maximize the number of errors and warnings you can log, consider removing unique identifiers such as:

  • User IDs
  • X, Y, Z location coordinates
  • Asset IDs

Resolving Errors and Warnings

To resolve errors and warnings, consider the following debugging steps:

  • Review the stack trace: Review the stack trace for the error or warning if it exists.
  • Check recent updates: Check if there's been a recent update and consider rolling it back if the metrics impact is severe.
  • Use built-in testing tools to troubleshoot:
    • Developer Console for viewing error and log messages and detailed information on memory and networking.
    • ScriptProfiler for identifying scripts that take up the most resources.
    • MicroProfiler for viewing unoptimized portions of your experience visually. Gather user feedback from your community.
