Description

I’m facing two issues with exceptions occurring in a web page loaded in BrowserWindow started with contextIsolation: true and nodeIntegration: false (Sentry is initialized as the first thing in a preload script):

• Unhandled exceptions are not sent to Sentry at all – maybe the 'error' event handler is not working when set up in the isolated context
• To capture exceptions manually, I expose Sentry.captureException in window by contextBridge.exposeInMainWorld, but any exception passed to it goes through the context isolation machinery, which creates a new Error object that only has a message property – stacktrace and error type is lost.

How should we deal with this? Loading and initializing only @sentry/browser in the actual webpage instead of the preload script would work, but then we lose all Electron breadcrumbs etc.

Sorry, I guess I wasn‘t very clear. The problem is with errors occurring in the main process, your test case only tests an error in the isolated renderer. I am calling init in all three, as per your advice from before, so events get submitted. The issue is that I call

Sentry.configureScope(scope => {
    scope.setUser({ id });
});

in the isolated renderer, and then at some point in the future, if an exception is thrown in the main process and sent to Sentry, it doesn’t have the user info that was provided before.

If I call

Sentry.getCurrentHub().getClient()._backend._setupScopeListener();

in the isolated renderer right after calling init, then all errors that occur in main will have that user info, breadcrumbs etc.

Does that make sense?

WIth 2.4.1 I still have the same problem. I force the main process to crash, but it still doesn’t get the scope and events from my sentry (react) implementation in the html context.

It seems that sentry-electron and sentry-react don’t work together. I tested it with sentry-electron in the html context instead, and then the scope and events are indeed copied over. Now I have to enable nodeIntegration as a workaround, which I don’t like. Do I have to do something special to integrate sentry-react with sentry-electron?
