Regrading the device custom attributes through sample app, app getting crash with 195 error, But in iOS its working fine

[NagendraMudadla]

Hi Team,

I added the one smart Wi-Fi light device through matter while using the your sample app. While controlling and reading the on off its working fine. But while reading the attributes the below errors are observed also app getting crashed.

FATAL EXCEPTION: main
Process: package PID: 30323
chip.devicecontroller.ChipClusterException: CHIP cluster error: 195
Suppressed: kotlinx.coroutines.internal.DiagnosticCoroutineContextException: [StandaloneCoroutine{Cancelling}@9b56298, Dispatchers.Main.immediate]

We tried different methods, but the same issues occurs every time. Please look into it and provide the solution for this?

No still we are facing this custom attribute reading?
