GoogleCloudRun不加载.env文件

我花了最近几天的时间试图找出我做错了什么，但我仍然无法弄清楚，因为我能够flask run使用docker-compose up --build. 源代码在这里

我的问题是我的 Cloud Run 部署成功，但单击URL时服务不可用。我检查了日志，似乎我的环境变量没有正确加载：

line 7, in <module> from web_messaging.blueprints.user import user File 
"/web_messaging/web_messaging/blueprints/user/__init__.py", line 1, in <module> from 
web_messaging.blueprints.user.views import user File 
"/web_messaging/web_messaging/blueprints/user/views.py", line 3, in <module> from 
web_messaging.extensions import mongo, login_manager, c, bc File 
"/web_messaging/web_messaging/extensions.py", line 18, in <module> twilio_client = Client(TWILIO_SID,
TWILIO_TOKEN) File "/usr/local/lib/python3.9/site-packages/twilio/rest/__init__.py", line 54, in __init__
raise TwilioException("Credentials are required to create a TwilioClient") 
twilio.base.exceptions.TwilioException: Credentials are required to create a TwilioClient    

我有一个config/.env文件和一个config/settings.py. 我从加载ENV变量.env使用 load_dotenv()上我的config/settings.py。我决定在 my 中添加一些 print 和 try/expect 语句config/settings.py来查看变量的值。

设置.py

import os
from dotenv import load_dotenv
BASEDIR = os.path.abspath(os.path.dirname(__file__))

try:
    load_dotenv(os.path.join(BASEDIR, '.env'))
    print("OK")
    print(BASEDIR)
except Exception as e:
    print(str(e))

# Mongo Database
MONGO_URI = os.getenv('MONGO_URI')
TWILIO_SID = os.getenv('TWILIO_SID')
TWILIO_TOKEN = os.getenv('TWILIO_TOKEN')
print(MONGO_URI)
print(TWILIO_SID)

当我使用 Flask run、docker-compose 或 cloud-run 运行时：

• 该BASEDIR值是/web_messaging/config
• load_dotenv()通话过程中无异常

但是，有一个主要区别，它是我的 env 变量的值，例如MONGO_URI, TWILIO_SID。这些变量在使用flask run和时具有正确的值，docker-compose但在 Cloud Run 日志上没有。在 Cloud Run 上，这些变量等于None。

当我不使用 a.env并直接将我的变量的值放入 中时/config/settings.py，没有问题并且我的 Cloud Run 链接工作正常。我还尝试移到.env配置文件之外和其他几个位置，但我仍然遇到同样的问题。
