Flutter - RevenueCat - 存在凭据问题，请检查底层错误以获取更多详细信息，购买后出现错误

问题描述

我正在通过 RevenueCat 在我的 Flutter 应用程序中集成应用程序购买，并支持 Android 和 IOS。我已按照文档中提到的所有步骤进行配置 (https://docs.revenuecat.com/docs/creating-play-service-credentials)、添加订阅详细信息、创建权利、产品、收入猫仪表板中的产品。

在代码中，在 main.dart 中启动了收入猫平台，获取产品并获取正确的数据，启动购买并显示付款成功，但一旦返回应用程序，它就会显示错误（附上下面的日志) :

我收到了来自 Google Play 商店的第 1 份邮件收据，5 分钟后我收到了取消收据并显示了“未确认购买”的原因。

任何形式的帮助将不胜感激。谢谢..

解决方法

E/[Purchases] - 错误（28086）：?‼️ 存在凭据问题。检查潜在错误以获取更多详细信息。

该错误表明您上传到 RevenueCat 的 Play 商店凭据存在问题。通常，这是因为凭据在整个 Google 中传播可能需要一天以上的时间 - 因此，如果您最近设置了这些凭据，这可能是原因。

参考文档：

错误处理：https://docs.revenuecat.com/docs/errors#---invalid_credentials
Play 商店凭据：https://docs.revenuecat.com/docs/creating-play-service-credentials

我重新创建了 google 凭据并将新凭据与 Revenuecat 相关联，几个小时后它运行良好。
