Add ignore list to beforeSend callback

[DonikaV]

Hello guys, i am using both
import { datadogRum } from '@datadog/browser-rum';
import { datadogLogs } from '@datadog/browser-logs';
In my NextJS application and I see a lot of errors in the data dog console, I want to ignore some errors but it does not work.

This is what I have

const ignorePatterns = [
  /\/attributions\//, // Matches "/attributions/"
  /Load failed/i, // Matches "Load failed" (case-insensitive)
  /utm_source=/, // Matches "utm_source="
  /DatafileManager/, // Matches "DatafileManager"
  /_rsc/, // Matches "_rsc"
  /HierarchyRequestError/, // Matches "HierarchyRequestError"
  /Failed to fetch RSC payload for/i, // Matches "Failed to fetch RSC payload for" (case-insensitive)
  /\/attributions\/visits/, // Add this to match "attributions/visits"
];

inside the datadogLogs.init({}) I have added

 beforeSend: (event, context) => {
          const msg = event?.error?.message;
          const url = context?.http?.url; // Check if the event context contains a URL.
          console.log(url, msg);

          // Ignore based on the message or URL patterns.
          if (
            (msg && ignorePatterns.some((pattern) => pattern.test(msg))) ||
            (url && ignorePatterns.some((pattern) => pattern.test(url)))
          ) {
            return false;
          }

          // Optionally ignore aborted events.
          if (context && 'isAborted' in context && context.isAborted) {
            return false;
          }
        },

But my data dog still full of errors
Like

XHR error POST domain.com/attributions/events
Failed to load

How I can ignore this errors? Thanks

Hello @DonikaV,
FMU, the error you're trying to filter is an HTTP error. In this case to filter on the message "XHR error POST domain.com/attributions/events" you need to check event.message not event.error.massage.
