I tried to find the "real" reason for the problem, but I couldn't find it (yet)

Also, I'm sorry if this is not a Sentry but a https://github.com/pmndrs/react-three-fiber bug, I was not sure this belongs in here

I posted it as a Sentry bug, because even though the error seems to get thrown in Fiber https://github.com/pmndrs/react-three-fiber/blob/a457290856f57741bf8beef4f6ff9dbf4879c0a5/packages/fiber/src/core/utils.ts#L337, I have the feeling that Fiber has a problem because maybe Sentry has added some Sentry specific attributes to the canvas element, actually there is an ambientlight three fiber component (inside of the canvas) where sentry seems to have added attributes and this seems to be the initial cause

When I remove Sentry from the Next.js configuration then everything is OK (no error in the console)

Also this error is only happens, when Next.js runs in "production", in development there is NO error

I tried to disable sentry integrations like breadcrumbs dom and also disable replaycanvas but the sentry attributes kept being placed onto fiber components as well as the canvas element itself

I found another Issue afterall, which seems to be about the problem I describe: getsentry/sentry-javascript-bundler-plugins#530

EDIT: so yes, that Issue sentry-javascript-bundler-plugins #530 is about the same problem, disabling reactComponentAnnotation fixes the react three fiber problem

next.config.js:

export default withSentryConfig(nextConfig, {

    // Automatically annotate React components to show their full name in breadcrumbs and session replay
    reactComponentAnnotation: {
        enabled: false,
    },

});

As suggested in the sentry-javascript-bundler-plugins #530 Issue, a way to exclude some components would be really useful

Hey @chrisweb thanks for writing in!

We'll look into your issue next week as this week is Hackweek at Sentry (see #13421).

Hi, thanks for being patient! Since we have established that this is caused by getsentry/sentry-javascript-bundler-plugins#530 I'll close this issue and we'll track it over there. cc @0Calories
