Incomplete/missing replays for non-SPA (MPA)

[billyvg]

For non-SPA where there is normal browser navigation: we can lose chunks of the replay if the user navigates quickly in and out of pages. This leads to broken looking replays as we do not capture the follow-up screens because they never get sent at all. This can lead to false dead clicks as well (I'm guessing due to bfcache?).

This can be configured, maybe we need to state this more explicitly in docs, but you can set new Replay({ minReplayDuration: 0 }) to basically disable this check.

Not sure how that would affect dead clicks, though, because these are only sent after the timeout (7s) passed. So you'd simply not get any dead click if moving away before 7s, I think!

I'm may be in the minority here as we have an application that isn't a single page app, but I would suggest finding a way to make this work out of the box with what is the default behavior of a web browser and web page. Ideally without having to adjust a parameter that I may still want to have set to several seconds considering the fact that it (as far as I understand it) has a direct impact on cost.

I just tested this and it didn't actually help. Here is my Sentry.init:

Sentry.init({
  dsn: dsn,
  environment: window.Settings.environmentName,
  release: window.Settings.releaseName,

  integrations: [
    new Sentry.BrowserTracing(),
    new Sentry.Integrations.Replay({
      maskAllText: true,
      // Necessary to make this work with regular browser apps
      // https://github.com/getsentry/sentry-javascript/issues/9301
      // - Aaron, Thu Oct 19 2023
      minReplayDuration: 0
    })
  ],

  tracesSampleRate: 1.0,
  replaysSessionSampleRate: 1.0,
  replaysOnErrorSampleRate: 1.0,

  ignoreErrors: ["AbortError"],
  beforeSend: (event) => {
    if (ignoreEvent(event)) {
      return null
    }

    return event
  }
});

And here's a replay ID: 70816a3030b04ca3aa076791bbff3fdb

Am I doing anything wrong in my config?

Could you provide a link to your replay on Sentry SaaS, then I can take a look. What exactly is not working for you? Is the replay not being sent at all, or is there data missing, ...?
