我正在将laravel应用程序放入群集集群，这是所有相关文件

Docker堆栈文件

.env.prod文件

# NOTE: I only shows the .env.prod file because I am pretty sure I
# properly setup on the postgres master node side also because
# the migration I ran from within the app container works and
# I also check the table and seed data does present in the
# postgres master node data
# and inside the .env.prod.postgres only have 3 env vars, those are
# db name, db user and db password

APP_NAME="APP"
...
DB_CONNECTION=pgsql
DB_HOST=postgres_master
DB_PORT=5432
DB_DATABASE=app
DB_USERNAME=user
DB_PASSWORD=user
...

我可以部署堆栈，并且一切都以预期的方式进行设置。将所有容器旋转起来之后。我可以执行到app容器中并成功运行迁移，也可以执行到postgres_master容器中，并查看所有表和种子数据。

问题出在我进入0.0.0.0时，它显示了预期的登录屏幕。但是，当我输入凭据并按Enter键登录时，它向我显示此错误：

注意：堆栈文件不是完美的，并且尚未完成。我计划首先使一切正常，然后在生产使用之前对其进行改进。
