update : this work on an iPhone 8 but not on an iPhone 13

[SimonErm]

Can you provide the code of the initialization of "workerN", seems like something went wrong there. Can you reinstall the testapp on iPhone13 and test again?

[xeroxcsn]

Hello, I ran into this error on iOS and seems like it happens randomly.

i am not sure i am using the library in a right way, but it works most of the time.

the error has been logged on different iOS device, from iPhone 8 to iPhone 14 Pro, and the iOS version is from 15.4.1 to 16.3.1

here is the error and where it happens

TypeError: Cannot read property 'isBusy' of undefined

// Queue.ts
private async getJobsForWorker(workerName: string) {
        const { isBusy, availableExecuters } = this.workers[workerName];    // got error here
        if (!isBusy) {
            return await this.jobStore.getJobsForWorker(workerName, availableExecuters);
        } else {
            return await this.getJobsForAlternateWorker();
        }
}

i hope these information can help, and if you need more information plwase let me know, thank you

[SimonErm]

@xeroxcsn thank you for the information. Are you calling the removeWorker function somewhere in your code?

[anark]

I get this issue as well and am not calling removeWorker anywhere.

I noticed however that I consistently get this issue when running via dev-client in expo. When I make a release build the issue goes away. I believe it has something to do with running via dev-client
