• Hi, guys can you please share progress or resolution?
• We encountered same problem after we upgraded @sentry/browser from 7.108.0 lib to 8.31.0 (on the previous version, everything worked correctly)
  - EDIT: - Last working version is 8.17.0 after this, Sentry starts showing this error
• we encountered it only in native iOS app (running angular app wrapped in Capacitor)

After downgrading to 8.17, the error is gone. thanks pal.

We've encountered the same issue after upgrading to 8.34.0. I rolled back to our old version 8.26.0 and it worked again.

[mdsaifurrahmann]

I'm currently using the same version, 8.26.0 and this version is moderately vulnerable, like 8.17
But I didn't find any option, rather using this version.

exactly @kai-softr after downgrade , it's working fine

[JimJafar]

I have raised a new issue asking Sentry to update this thread with instructions on how to resolve this.
getsentry/sentry#79355

[Beauchaj]

Saw the issue on 8.33.0, however have got it working on 8.27.0

[lobsterkatie]

According to the internal support ticket, the problem had to do with Firebase, specifically this: firebase/firebase-tools#1661.

I'm going to reopen this, but I'm also going to move it to the SDK repo, since that's where the incompatibility lies.

@JimJafar @Beauchaj Could someone provide a minimal reproduction for this?

@JimJafar @Beauchaj Could someone provide a minimal reproduction for this?

I don't believe its limited to firebase. I came across the problem on an Ionic react project, using sentry/capacitor.

Capacitor and Ionic versions

    "@capacitor/core": "^6.1.2",
    "@capacitor/ios": "^6.1.2",
    "@ionic/react": "^8.1.0",

This (excerpt from package.json) succeeds

"dependencies": {
    "@sentry/capacitor": "1.0.0",
    "@sentry/cli": "^2.38.0",
    "@sentry/react": "8.27.0",

While this fails with the error in the topic.

"dependencies": {
    "@sentry/capacitor": "1.0.1",
    "@sentry/cli": "^2.38.0",
    "@sentry/react": "8.33.0",

[chargome]

@Beauchaj thanks for pointing that out, but we'll still need to wait for a reproduction to debug this issue.

[thomanil]

@chargome I am seeing the same thing inside a Capacitor app, when using the Capacitor http plugin - https://capacitorjs.com/docs/apis/http It works fine in the same capacitor project when I do not use that http plugin (capacitor/http patches or modifies xhr, and is very commonly in use for projects that use cookie-based auth/credentials.)

I can try to create a minimal reproduction skeleton project tomorrow, if that helps.

[andreiborza]

@thomanil thanks for chiming in. Yea a reproduction would help for sure, thanks!

[thomanil]

Did not get around to it yesterday but will be able to one of next few days :)

[thomanil]

@andreiborza @chargome @muuvmuuv Reproduction here: https://github.com/thomanil/sentry-on-capacitor-patched-xhr-crash-reproduce/tree/main

(Have tried to make it as easy as possible to set up, but let me know if you have any trouble!)

[andreiborza]

@thomanil thanks for that. Taking a look.

[andreiborza]

@thomanil this has been fixed with #14140. Please upgrade the sdk to the latest. I tested it out with your reproduction and got the successful init message with the latest browser sdk.

[thomanil]

So it does not just fail silently, error reports do make it out in latest release?

[andreiborza]

@thomanil yep
