Joined a webinar as a host, my application crashed by the SDK trouble when an other attendee raised a hand.

Hey @IDevDev,

Thanks for using the dev forum!

That does not sound good. Let me try and reproduce, stay tuned.

Thanks!

Hey @IDevDev,

I have not been able to reproduce this one. Are you using a physical iPad air 4? Does this happen on handset as well?

Thanks!
Michael

Are you using a physical iPad air 4?

Yes, I use a physical iPad Air 4.

Does this happen on handset as well?

I don’t know. I have not try it on handset yet.

I am going to try to reproduce this issue on other physical machines.

Hey @IDevDev,

How many people are in the webinar when this happens?

Thanks!
Michael

Hey Michael.

There were only two people, a host and an attendee.
The issue happened when I tested my app.

In addition to iPad Air 4th, the issue happened in iPad Pro 5th (this machine’s core is M1 chip).
I have not tested iPhones, yet.

Thanks.

Hey @IDevDev,

In your application do you have the onSinkMeetingUserRaiseHand callback implemented? If so, can you put a breakpoint there and see if it gets called before the app crashes?

Thanks!
Michael

Hey Michael.

In your application do you have the onSinkMeetingUserRaiseHand callback implemented?

Yes, my app have the onSinkMeetingUserRaiseHand callback.
And it works well in meetings.

If so, can you put a breakpoint there and see if it gets called before the app crashes?

In the issue case, the method never have called before it crashed.

Thanks.

Hey @IDevDev,

I see. Let me try to reproduce again.

Michael
