Hi @gotenxds , in order to make sure this lands on the right team, could you please share which Sentry SDK and version you are using, and what your Sentry SDK setup is?

[gotenxds]

hi @InterstellarStella Thanks for the quick reply, of course
We are using "@sentry/react": "^7.105.0"
Our setup looks like so

function beforeSend(event) {
  Object.assign(event, {
    // Add any additional event information here
  });

  return event;
}

const sentryConfig = {};

function prepareSentryConfig(history) {
  Object.assign(sentryConfig, {
    beforeSend,
    integrations: [
      Sentry.replayIntegration(),
      Sentry.reactRouterV5BrowserTracingIntegration({
        history,
        routes: routeDefs.flattenedRoutes,
        matchPath,
      }),
    ],
    replaysSessionSampleRate: 0.01,
    replaysOnErrorSampleRate: 1.0,
    ignoreErrors: ['ResizeObserver loop limit exceeded'],
  });
}

function initializeSentry(userData) {
  if (__PRODUCTION__ && !__IS_CI__) {
    Sentry.init({
      ...sentryConfig,
      dsn: frontendConfig.sentryDsn,
      environment: frontendConfig.environment,
      release: frontendConfig.release,
      tracesSampler: 0.4,
    });

    Sentry.setUser({ id: userData.sub, username: userData.username });
    Sentry.setTag('company_id', userData.company_id);
    Sentry.setTag('company_name', userData.company_name);
  }
}

Thank you @gotenxds ! I will be transferring this issue to the correct repo for triage.

Hi, when are you calling initializeSentry?

Hi @lforst, it depends, we have a few entry points to the system, but generally on first page load
