Impressive 🙂 I think this is only possible if we load before the runtime globals gets set?

cristianoccazinsp · 2022-02-16T15:11:59Z

I'm amazed as well. I've only seen one user with this issue with an old device, so perhaps a slow start and a race condition?

The user still managed to trigger the issue 4 times, and then probably gave up.

The issue also happens right when importing realm:
import Realm from 'realm';

Could it be related to inlineRequires: true ?

fronck · 2022-02-17T13:30:18Z

@cristianoccazinsp Thanks for reporting -- we'll look into it. Please let us know if you dig out more information.

"jsc-android": "^250230.2.1" solved issue for me, as i was having issue in android

takameyer · 2022-03-02T08:09:25Z

@laxminarayan192 What version of jsc-android were you using before? I am a bit confused that updating JSC on android would fix your issue on iOS.

takameyer · 2022-03-02T10:28:24Z

It appears globalThis support was added in iOS version 12.2 (WebKit/WebKit@2b424f0). So that would explain why users running on old devices would run into this issue.

cristianoccazinsp · 2022-03-02T12:34:04Z

I'm getting the issue only on iOS. But you are right, these are all old devices.

laxminarayan192 · 2022-03-02T14:02:03Z

@laxminarayan192 What version of jsc-android were you using before? I am a bit confused that updating JSC on android would fix your issue on iOS.

I was using jsc-android: "241213.1.0",

takameyer · 2022-03-02T14:18:53Z

@cristianoccazinsp I created a PR that might solve the issue. Unfortunately, I do not have a good way to test this.

takameyer · 2022-03-02T14:29:51Z

Although, the ipad mini mentioned above does have the ability to upgrade to 12.5, which would also fix the issue

cristianoccazinsp · 2022-03-02T14:39:43Z

It's not easy to tell users to upgrade their ancient devices :D

takameyer · 2022-03-03T08:14:19Z

@cristianoccazinsp That is true 😆 A fix is on the way.

@takameyer @kraenhansen I seem to be seeing the same crash logs with Realm 10.20.0-beta.4. Wasn't this resolved? Maybe not released yet?

@cristianoccazinsp I believe this was released with 10.20.0-beta.5 and 10.16.0

cristianoccazinsp · 2022-06-13T12:27:39Z

@takameyer we have released a new version using 10.20.0-beta.5, yet the error still shows.

tomduncalf · 2022-06-13T15:33:54Z

Hey @cristianoccazinsp, sorry to hear you are still having issues. I'm going to try Realm out on a device with iOS 11 to see if I can reproduce the issue and I'll let you know how it goes.

tomduncalf · 2022-06-13T16:14:23Z

I was able to reproduce this on iOS 11, so will investigate further tomorrow.

cristianoccazinsp · 2022-06-13T16:16:57Z

Thanks for the quick review!

cristianoccazinsp · 2022-06-14T12:19:27Z

Not sure if just a coincidence, but beta.5 seems to be having this issue more frequently than beta.4. After the release, the error is being reported much more frequently.

tomduncalf · 2022-06-14T15:16:54Z

Hey @cristianoccazinsp, I think that's a coincidence, from what I can see this would just 100% not work on iOS 11 (which I tested on) and from the sounds of things 12. I've got a fix in review, so hopefully we can get that into the next Hermes branch release (which is currently blocked on some test issues but we are working to resolve those this week)

fronck · 2022-06-30T07:37:17Z

@cristianoccazinsp We've closed this issue for now. If the fix merged in the hermes branch doesn't work for you, feel free to re-open.

cristianoccazinsp · 2022-07-01T20:22:16Z

@fronck what beta version can this fix be found at?
