Worklets installation not working. Fatal signal 6 (SIGABRT), code -1 (SI_QUEUE) in tid 17909 (mqt_js)

[JohnFTitor]

Hello Team

Thanks for bringing this package. I've been trying to install it in my JavaScript project (no typescript) and I've been having issues not being able to execute the example.
I've installed it, manually linking it (my project has problems with auto-linking, so I manually added it to the MainApplication.java file). It seems to be capturing the function correctly, but it fails with an error Fatal signal 6 (SIGABRT), code -1 (SI_QUEUE) in tid 17909 (mqt_js) when executing the code.

I'm trying the example as follows:

import { Worklets } from 'react-native-worklets-core'

const fibonacci = (num) => {
        'worklet'
        if (num <= 1) return 1
        return fibonacci(num - 1) + fibonacci(num - 2)
}
              
const worklet = Worklets.createRunInContextFn(fibonacci)
            
worklet(50).then((result) => {
       console.log(`Fibonacci of 50 is ${result}`)
})

There shouldn't be a difference compared to the example typescript one, except for removing the types.

This is the error I see in my console, before it crashes

And this is the logcat

Is there something I'm missing here?
Also, I'm not using React's new architecture

Thank you!

Same problem

[MAKARD]

have the same

I think this is because you're trying to recursively call fibonacci. Recursion is not yet implemented, so use a normal for loop instead.

@JohnFTitor, @dattv-unstatic, @MAKARD Are you using V8 as javascript engine inside your project?
