Javascript grouping for errors across user profile pages

SDKs
1

Hi All,

I’m running a website which has URLs like:
https://domain.com/USERID-USERNAME

This page triggers errors when JS resources do not load properly, however these errors are grouped per page which means I have the same error repeated for every user affected.

Is it possible to set a Page Alias or similar so sentry groups all these errors under a more generic “profile page” rather than “profile for user X”?

Thanks all!

Michael

You can use setFingerprint as described in this blogpost: https://blog.sentry.io/2019/01/17/debug-tough-front-end-errors-sentry-clues

Sentry.withScope(scope => {
  scope.setFingerprint(['https://domain.com/USERID']);
  Sentry.captureException(error);
});

If you want to group all issues together globally on this specific site you can use:

Sentry.configureScope(scope => {
  scope.setFingerprint(['https://domain.com/USERID']);
});

that means that all errors that occur afterward will have this fingerprint so be aware of that.

The fingerprint itself tells sentry how to group errors.

Hope this helps.

Thank you very much for the information about fingerprints, I will give it a try and report back. :slight_smile:

This works really well, thanks for your help. Here’s the code I’m using in production when pages supply a fingerprint:

Sentry.configureScope(scope => {
    scope.setFingerprint(<?= json_encode([$fullUrl . '/' . $fingerprint]) ?>);
});
