如何解决kotlin firebase 数据库无法上传？

开发过程中遇到kotlin firebase 数据库无法上传的问题如何解决？下面主要结合日常开发的经验，给出你关于kotlin firebase 数据库无法上传的解决方法建议，希望对你解决kotlin firebase 数据库无法上传有所启发或帮助；

我有一个小项目正在运行一个应用程序来跟踪我的 LP 和 cd

事情是......我想实现一个 Firebase 数据库来存储所有数据。这不是我第一次做这样的事情......这是我第一次被它困住了。

这是“添加项目”屏幕的基本代码。这个想法是我能够通过文本视图、微调器、图像等将一些数据附加到项目中。

该脚本在“上传图像”部分之前完美无缺……之后它将运行 firebase 上传代码……但没有任何反应。成功和失败日志都没有给出任何输出。

有人能帮我解决这个问题吗？
