Describe the bug | 问题描述

按照官方Zeabur部署教程：https://waline.js.org/guide/deploy/zeabur.html一步步进行部署，到最后生成自己的域名后进行访问。网站能够成功进入，但是评论无法发布、用户无法登录，出现500: Not initialized报错。

官方也并没有给出如何修复此问题的解决方案。

这个是没有环境变量的问题，看下 MONGODB_URI 这个环境变量是否有，zeabur 应该会默认创建的。

This is a problem because there is no environment variable. Check whether the MONGODB_URI environment variable exists. Zeabur should create it by default.

好的，感谢回复！已经成功修复问题。

OK, thanks for the reply! The problem has been successfully fixed.

I am facing an issue where the MONGODB_URI environment variable is missing, even though MONGO_URI is present. What steps should I take, and where can I define the MONGODB_URI environment variable? @lizheming

[jongsh]

The part of environment variables of mongodb is like this:

MONGO_HOST=${CONTAINER_HOSTNAME}
MONGO_INITDB_ROOT_PASSWORD=${PASSWORD}
MONGO_INITDB_ROOT_USERNAME=mongo
MONGO_URI=${MONGO_CONNECTION_STRING}
MONGO_PASSWORD=${MONGO_INITDB_ROOT_PASSWORD}
MONGO_PORT=${DATABASE_PORT}
MONGO_USERNAME=${MONGO_INITDB_ROOT_USERNAME}
