Sentry says to the user that showReportDialog data has been sent when it wasn't

[ChALkeR]

Recreated from #2072 per @kamilogorek request.

Important Details

How are you running Sentry?

• Saas (sentry.io)

@sentry/browser@5.2.1 was used.

Description

Consider an example code for manual issue reporting:

Sentry.showReportDialog({ eventId: window.Sentry.captureMessage('test') })

It shows the report dialog, the user fills the fields in, and then this is shown:

User thinks that the report is submitted.

But in fact, nothing was sent anywhere, because at the very first step (during captureMessage) the POST request to https://sentry.io/api/***/store/ was blocked by uBlock with net::ERR_BLOCKED_BY_CLIENT, and Sentry wan't even able to detect that.

||sentry.io/api/*/store/? is in AdGuard Tracking Protection list (probably also some more).

Steps to Reproduce

1. Add Sentry to an example webpage (client-side)
2. Open it in Chrome, install uBlock with fairly default filters (AdGuard Tracking Protection), or block those POST requests by other means if that doesn't work.
3. Try to use Sentry.showReportDialog (example code above), the same applies to example directly taken from https://docs.sentry.io/enriching-error-data/user-feedback/

What happens

The user is shown a confirmation that their report has been sent when it actually wasn't.

What you expected to happen

Either of the following:

• the data should be actually sent,
• the final message should indicate that the data could not be sent (not ideal)
• the user should be warned at the very beginning that the report has been blocked by their browser setup

Possible Solution

Detect that the POST has failed and abort the report dialog, possibly replacing it with a corresponding message.

Has anyone found a fix for this yet?

@kamilogorek - I think this should be possible. We may also try using the beacon API too.

I have this Problem also on one Website. XHR is blocked can not enable it

This issue has gone three weeks without activity. In another week, I will close it.

But! If you comment or otherwise update it, I will reset the clock, and if you label it Status: Backlog or Status: In Progress, I will leave it alone ... forever!
