问题描述
我最近发布了我的应用程序的新版本，在更新到它时，应用程序立即崩溃，原因是“io.realm.exceptions.RealmMigrationNeededException：由于以下错误需要迁移”
我的目标是更新应用程序，在不崩溃的情况下运行领域迁移。
应用因 io.realm.exceptions.RealmMigrationNeededException 崩溃：由于以下错误，需要迁移：
Property 'HistoryLogModel.bytes' has been made optional. (unmodified for this release)
Property 'StatusDataModel.data' has been made optional. (unmodified for this release)
Property 'TelemetryLogModel.data' has been made optional. (unmodified for this release)
Property 'TelemetryLogModel.timeStamp' has been made optional. (modified for this release and migration is created)
除 TelemetryLogModel.timeStamp 外，其余属性均未针对此版本进行修改。
应用的原始版本有 io.realm:realm-gradle-plugin:7.0.2
最新版本有 io.realm:realm-gradle-plugin:7.0.8
查看更改日志，这两个版本之间没有重大更改。
这是堆栈跟踪：
