我在Crashlytics收到崩溃报告，但有以下例外情况。
致命异常：NSInvalidArgumentException核心数据：无处不在：
无法处理事务日志位置:: / var / mobile / Library / Mobile 文档/ 446F8WSMM7〜....〜/ CloudLogs / CA12AE9B-73E3-4D91-A213-7D1C9B4FBD2C /移动〜74894246-275A-40C0-B533-679A3FF50584 / CA12AE9B-73E3-4D91-A213-7D1C9B4FBD2C / pqMAN_WUmVCDyym_K497rYvOLRFh9LsAdjD6Ru1IiTA = /移动〜74894246 -275A-40C0-B533-679A3FF50584.0.cdt， 并不表示实际代表交易日志位置。
我无法重现此问题，我不确定可能导致此问题的原因。有没有人经历过这个并知道如何解决它？
这是我获得异常的线程的堆栈跟踪。
