tns::Runtime::GetAppConfigValue(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> >)

Hi, I found in my Crashlytics log a lot of this issue. Could you help to check what is the caused?

Below is the stack traces from Firebase

Start by tracing the tns::Runtime::GetAppConfigValue entry in the stack trace and its call from tns::NativeScriptException::OnUncaughtError. Review the surrounding iOS runtime and Objective-C interaction, then determine the crash cause; done means a confirmed root cause with a targeted fix or reproducible diagnostic details.
