JVMTI is null when using ClassLoader.choose of another classloader

[numnum17]

Hi,
I'm trying to perform instance choose in different class loaders -

export function chooseAll<T>(className: string, callbacks: ChooseCallbacks<T>) {
    Java.enumerateClassLoadersSync().forEach((loader: any) => {
        const cLoader = Java.ClassFactory.get(loader)
        Logger.debug(loader)
        Logger.debug(cLoader.toString())
        
        try {
            cLoader.choose(className, {
                onMatch(instance) {
                    return callbacks.onMatch(instance)
                },
                onComplete() {
                    callbacks.onComplete()
                }
            })
        } catch (e: any) {
            if (!e.toString().includes("java.lang.ClassNotFoundException"))
                Logger.error(e.toString())
        }
    })
}

When running, I'm receiving an error message -

TypeError: cannot read property 'iterateOverInstancesOfClass' of null
