如何调试此 Xcode 堆栈跟踪

Question

Flutter 应用程序在 <1% 的设备（所有版本和型号）上请求通过包（health_kit_reporter 和 HealthKitReporter）写入 Apple Health 的授权时发生崩溃。

有没有关于崩溃原因的信息？或者在使用 Xcode?

调试期间是否有重现错误的技巧

Answer 1

我在我的应用程序中偶然发现了这个错误。我还没有验证这一点，但看起来这个问题是由 call in encodeErrorEnvelope 引起的，它试图写入错误细节，如果这样的错误细节不可编码，它会使应用程序崩溃。

Answer 2

此错误已通过此处的更改得到修复： https://github.com/VictorKachalov/health_kit_reporter/pull/25/files
