React Native iOS Firebase匿名认证[auth/internal-error]问题求助

生产环境中，5%的用户调用auth().signInAnonymously()时触发[auth/internal-error]错误，提示“An internal error has occurred, please try again”，仅生产环境出现该问题，开发环境无异常。

问题详情 #

应用Firebase认证已按官方文档配置，开发和生产环境使用两个独立Firebase项目，共用bundle identifier，通过AppDelegate.mm加载对应环境的GoogleService-Info.plist文件。仅生产环境出现该错误，影响5%的用户。

额外信息 #

• 多数用户可正常完成认证；
• 用户量激增时错误频率明显上升，疑似高并发相关；
• 部分用户重试多次或几小时后重启应用可成功认证；
• 德国用户出现该错误的频率最高；
• 多数用户遇到错误后无法立即成功，少数需重试20次或次日重启才行；
• 用户遇到auth/network-request failed错误时大多能成功认证。

已排查内容 #

• 联系GCP团队检查日志，Identity Toolkit无服务器错误记录；
• 无法在开发或生产环境的iOS测试设备上复现问题；
• 移除AppCenter和CodePush后问题未改善；
