@Meherdeep : Getting an exception on the test app as well:

@Meherdeep : here's the code repo where it is crashing for us on ios : https://github.com/luvishq/agora_poc

[luvishq]

Can you point out what's wrong with it ?

[Meherdeep]

Hey @luvishq, I tried building your app with the credentials you provided and it was missing the token because of which it was throwing an error. I tried building the same app with my credentials and it worked fine.

Can you try generating a temp token from your console and use it in the AgoraConnectionData function?

[luvishq]

Hey @Meherdeep ,

Sure here's the temp token : 00655285ac327784e0aa74269eba5b7ff20IABcF/WP59Flv7XNB+4tjYqK05X/fdaE5hg6Xgfsk0RD7VrHnl0AAAAAEABQGUv2XVgMYQEAAQBdWAxh

Just wanted to confirm that you tested on a real phone right ? for me it's crashing ios 14.5.

I tried with a temp token but it failed

Edit
@Meherdeep : can you also confirm , if after you close the video window , the app doesn't crash because sometimes it launched the video window but crashed with the above exception after closing the window.

[Meherdeep]

@luvishq Yes, I built it on a physical device running iOS 14.6 and it works perfectly. I tried closing the video window by pressing the disconnect button (I guess that's what you meant by closing the video window) and that brings me to an empty screen.

I wasn't able to reproduce the crash message that you shared. Can you try adding breakpoints in your code to possibly see where the code is failing?

hey @Meherdeep , i fixed this issue, something related to ios configuration on our end. It's working great. Thank you so much for being patiently helping us :)
