I'm very sorry that i cannot provide more info on this, but we really couldn't find a way to reproduce.

Here's all the info we got:

1. It's only related to JavaScriptCore on iOS 17 and above.
2. It's not related to sepecific framework or application.
3. Once the error is triggered, it will keep occurring until the application is restarted.
4. The error stack is different each time it occurs.
5. The first line of the error stack is `[native code]` even if the actual stack is a javascript function.

Here is some error stack samples:

```
Invalid character: '\0'

```

```

```
