Permission denied to access property "apply" (Firefox)

[lerela]

Is there an existing issue for this?

• [X] I have checked for existing issues https://github.com/getsentry/sentry-javascript/issues
• [X] I have reviewed the documentation https://docs.sentry.io/
• [X] I am using the latest SDK release https://github.com/getsentry/sentry-javascript/releases

How do you use Sentry?

Sentry Saas (sentry.io)

Which package are you using?

@sentry/nextjs

SDK Version

7.26.0

Framework Version

Next 12

Link to Sentry event

https://sentry.io/organizations/fasfox/issues/3787755937/

Steps to Reproduce

For 10 days, we have seen new errors pop up that do not seem to match user code as the exception Permission denied to access property "apply" is located in ./node_modules/.pnpm/@[email protected]/node_modules/@sentry/utils/esm/instrument.js. We've upgraded to 7.26.0 but the errors continue to happen.

At this moment I do not know if this means something is crashing as we've not been able to reproduce it ourselves.

It seems to only happen with Firefox, which sounds like #3344 but that has been fixed a while ago.

We have not been able to link those errors to application changes but we might be wrong, however the trace does not allow us to find the culprit.

Expected Result

No exception coming from Sentry code itself

Actual Result

Exception seems to be coming from Sentry SDK

Hi, thanks for reporting this. Right away, nothing really comes to mind about why this might be happening.

Just trying to narrow down the problem:

• Do you have iframes on your website?
• Can you share a bit more about how you initialize Sentry on your page?

[lerela]

Thanks for your reply.

We use Chatwoot (live chat) which I believe makes use of iframes, even though we do not use them directly.

We configure Sentry using your snippet (upgrade to 7.26 broke the build so we had to change it) and we use sentry.client.config.js looks like this:

Sentry.init({
  dsn: env('SENTRY_DSN'),
  enabled: process.env.NODE_ENV !== 'development',
  environment: process.env.ENVIRONMENT | "dev",
  ignoreErrors: [
    "ResizeObserver loop limit exceeded",
    "ResizeObserver loop completed with undelivered notifications"
  ]
});

Feel free to close this issue if you feel this is coming from our application, I am wondering why would the stack trace only show Sentry SDK but that could definitely be something on our side.

[lforst]

Ok what might be going on is that Chatwoot is using Sentry themselves inside the iframe and this is causing the issue. (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Errors/Property_access_denied)

Honestly, I am a bit lost myself at the moment how and why this is happening. We would definitely need to reproduce this somehow to fix it. We might also just do the same thing we did in https://github.com/getsentry/sentry-javascript/pull/3377 for the rest of the handlers.

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!

Hello, I have similar issues

We use on project "@sentry/browser": "^7.81.1", "@sentry/tracing": "^7.81.1"

Config looks like:

 Sentry.init({
    dsn,
    tracesSampleRate,
    release,
    integrations: [new BrowserTracing()],
    initialScope: { tags: { service } },
    ignoreErrors: [ROUTE_CHANGE_ABORT_ERROR_MESSAGE],
    beforeSend: filterSentryData,
});

Can you help please ?

[lforst]

@AnnPanasyuk Can you verify that the error is coming from within the SDK in your case? Thanks! I am asking because nothing you reported really points towards that.

[AnnPanasyuk]

We use next in our project which loads by chunks sentry also

[lforst]

@AnnPanasyuk what I meant is, can you verify that the error is actually caused by the SDK? It looks like the error is coming from your own code somewhere. I don't think there is anything we can do.
