Could you share the code in use for this, along with an overview of when this error is encountered? For example, does it happen when connecting to Channels / receiving events?

[mohamedsalah414]

I don't know when and how it happens, I have this repetitive crashes daily in firebase crashlytics

Hi @benw-pusher. I am facing this issue of app crashing as well on a test flight build on my client's iphone. But I have figured the app crashes only when the iphone is running on latest ios version 17, as the app works fine on my iphone 13 pro max with ios 16. I have been using the same code for the app provided in the example app and its working as well. So I don't need to provide you any example code because app crashes with same code on ios 17 but works fine on earlier versions. I am using latest available version 2,2,0 of the package. Kindly help us resolve the issue as our team is stuck for release this app to the app store. Thanks is advance.

I have tested the example app on an iOS 17 device and no crashes are observed. Do you know when this issue occurs? For example, subscribing to a particular channel type / receiving an event?

Hi @saurabhunify I am facing the same issue. did. u find any solution?

[kadersaka]

the crash was caused by the onAuthorizer passed when initiating pusher. it was not returning expected type of response that was casted in the library code
