Issue
I am seeing <unlabeled event> entries in Sentry (React JS/web app), and I am unsure why these events are not being labeled correctly.
Resolution
Common Causes of <unlabeled event> Entries:
Missing Data in Events:
<unlabeled event>occurs when events lack the information Sentry uses to generate labels, such as:Exception information for error events.
Message information for info events.
Custom
beforeSendLogic:If you are using a
beforeSendcallback, verify that it is not modifying or removing critical event data (e.g., exceptions).Misconfigured scrubbing logic in
beforeSendcan inadvertently strip event details, resulting in unlabeled events.
Old SDK Versions or Manual Event Reporting:
Ensure you are using the latest version of the Sentry JavaScript SDK.
Events sent using outdated SDK versions, the API, or manual SDK calls may lack required fields.
Steps to Resolve:
Update to the Latest SDK Version:
Confirm that your application is using the latest version of the Sentry JavaScript SDK.
Check for Custom
beforeSendLogic:Review the
beforeSendcallback in yourSentry.initconfiguration.Temporarily disable the
beforeSendlogic to see if it resolves the issue.
