在Heroku上部署Python 3（fastapi）应用程序不断失败

这是我第一次使用Heroku，我正在尝试部署使用FastApi构建的Python应用程序。在本地运行该应用程序时，一切都很好，代码本身应该没有问题。

我创建了包含： Web：Uvicorn App.main：App -host = 0.0.0.0 -port = $ {port：-5000}

我已经为git添加了所有内容，做了git commit-command，并将其全部推向了git。

当一切都被签入时，我将其推向Heroku： Git推动Heroku Main。

Dyno/App获得“构建成功”，从我看到的端口分配的日志中，但是在尝试浏览应用程序时仍会收到错误代码。

最常见的是H20-应用程序启动时间，但是我也看到了错误代码R10，最后H10 =应用程序崩溃了。另外，它记录了“ tkinter”＆lt; - 应该在Python的安装过程中解决的问题吗？

当我将启动时间增加到+120秒时，出现H20。当我重置默认为60秒时，它只会记录R10 + H10。

It's my first time using Heroku and I'm trying to deploy a python app which is build using Fastapi.
Everything is working fine when running the app locally and there should be no problems with the code itself.

I've created my Procfile which contains:
web: uvicorn app.main:app --host=0.0.0.0 --port=${PORT:-5000}

I've added everything to git, did the git commit-command and pushed it all out to git.

When everything is checked in to git, I'm pushing it out to Heroku:
git push heroku main.

the dyno/app gets "build succeeded" and from the logs I'm seeing a port being assigned, but I'm still getting error codes when trying to browse the application.

The most frequent one being H20 - App boot time, but I'm also seeing error code R10 and finally H10 = App crashed.
Also, it logs a problem with "tkinter" <- this should have been addressed in the installation proccess of Python?

When I increase the boot time to +120 seconds, the H20 appears. When I reset to default 60 seconds, it just logs the R10 + H10.

print from the heroku log 1

print from the heroku log 2
