我可以看到一些提及“连接槽”，但在检查我的 SQL 服务器状态时，我可以看到没有太多连接 - 毕竟这是一个测试服务器。

我还可以看到“EROFS：只读文件系统”错误，这表明 Strapi 正在尝试写入磁盘。但是，我不明白为什么自上次部署以来这会发生变化。我什至尝试回滚到上一个版本（正在运行）并部署那个版本，但仍然没有运气！

非常感谢任何帮助，谢谢！

【解决方案1】：

通常情况下，我会在其他人回答之前解决我自己的问题 :)

按照此处的说明，我能够降级到 Strapi v3.2.4：https://strapi.io/documentation/v3.x/guides/update-version.html#upgrade-your-dependencies

按照所有这些步骤并再次运行 gcloud app deploy 后，一切正常！
