여전히 index.html 파일을 찾을 수 없다는 오류가 발생하고 있습니다. 이 문제는 보통 index.html 파일이 존재하지 않거나, 잘못된 경로에 배치된 경우에 발생합니다. 다음과 같은 방법으로 문제를 해결해 보세요:

파일 위치 확인:
- index.html 파일이 templates 디렉터리에 있는지 확인하세요. 파일이 없다면 추가해야 합니다.

프로젝트 구조는 다음과 같아야 합니다

├── app.py
├── requirements.txt
├── Procfile
├── templates/
    ├── index.html
    ├── result.html

파일 추가 후 Git에 반영:

index.html 파일을 templates 폴더에 추가한 후, 변경 사항을 Git에 반영하고 다시 푸시해야 합니다.

git add templates/index.html templates/result.html
git commit -m "Add index.html and result.html to templates directory"
git push heroku main

파일 경로 확인:
- Flask는 템플릿 파일이 반드시 templates/ 폴더에 있어야 합니다. 파일 경로가 잘못된 경우 index.html을 찾을 수 없게 되니, 반드시 올바른 경로에 위치해야 합니다.

이 과정을 통해 Heroku에서 index.html을 찾을 수 있게 됩니다. 추가로 문제가 있거나 더 도와드릴 부분이 있다면 알려주세요!

프로젝트 구조를 확인한 결과, templates 폴더에 index.html과 result.html 파일이 올바르게 배치되어 있는 것 같습니다. 이 경우에도 Heroku에서 템플릿을 찾지 못하는 문제가 발생하는 몇 가지 원인을 살펴보고 해결해 보겠습니다.

Git에 올바르게 반영되지 않은 파일 확인:
- 모든 파일이 Git에 커밋되어 있는지 확인하세요. 특히, index.html과 result.html 파일이 올바르게 Git에 추가되었는지 확인해야 합니다.

git status

만약 index.html 파일이 Git에 추가되지 않았다면, 추가하고 푸시하세요.

git add templates/index.html templates/result.html
git commit -m "Add index.html and result.html"
git push heroku main

템플릿 캐시 문제:

가끔씩 템플릿 파일이 캐시되어 발생하는 문제일 수 있습니다. Heroku에서 앱을 강제로 다시 시작해 볼 수 있습니다.

heroku restart

경로 확인 및 대소문자 확인:
- 파일명이나 경로의 대소문자가 일치하지 않으면 템플릿을 찾지 못할 수 있습니다. templates 폴더와 파일 이름(index.html, result.html)의 대소문자가 정확한지 확인하세요.
추가 로그 확인:
- 여전히 문제가 해결되지 않는 경우, 추가 로그를 확인해 더 많은 힌트를 얻을 수 있습니다. heroku logs --tail을 사용해 실시간으로 로그를 확인하면서 추가적인 오류가 있는지 찾아보세요.

이 단계를 시도한 후에도 문제가 해결되지 않으면 알려주세요. 추가적인 문제 해결을 도와드리겠습니다.

PS C:\_Fractal Trail> git status
On branch master
nothing to commit, working tree clean

현재 git status 명령어에서 “nothing to commit, working tree clean” 메시지가 나타났으므로, 모든 변경 사항이 이미 커밋되어 있다는 의미입니다. 따라서 index.html 파일은 Git에 올바르게 커밋되었고, Heroku에도 푸시된 상태입니다. 그럼에도 여전히 Heroku에서 템플릿을 찾지 못하는 이유는 몇 가지 가능성이 있습니다.

Heroku 배포 캐시 문제:
- Heroku의 캐시 때문에 변경 사항이 제대로 반영되지 않았을 수 있습니다. 이를 해결하기 위해 캐시를 무시하고 다시 배포해 볼 수 있습니다.

git commit --allow-empty -m "Trigger Heroku redeploy"
git push heroku main

디렉터리 구조 문제:

디렉터리 구조를 다시 확인해 보세요. templates 폴더와 그 안의 파일들이 Heroku에서 접근할 수 있는 위치에 있는지 확인해야 합니다. 구조가 잘못되면 템플릿을 찾을 수 없습니다.

템플릿 파일 권한 문제:

파일 권한 문제로 인해 Heroku에서 템플릿을 읽지 못하는 경우도 있을 수 있습니다. 권한이 잘못 설정되었다면, 다음 명령어로 모든 파일 권한을 확인하고 수정하세요.

chmod -R 755 .

Heroku 로그 추가 확인:
- heroku logs --tail 명령어로 추가적인 오류나 힌트가 있는지 확인하세요. 특정 권한 문제나 접근 문제에 대한 추가적인 로그가 있을 수 있습니다.

위의 단계를 따라 진행해보시고, 문제가 해결되는지 확인해 주세요. 추가적인 로그가 있다면 다시 공유해 주시면 더 도와드릴 수 있습니다.

Heroku 로그에서 jinja2.exceptions.TemplateNotFound: index.html 오류가 계속 발생하고 있습니다. 이 문제의 해결을 위해 다음을 확인해보세요:

templates 디렉터리의 위치 확인:
- index.html 파일이 templates 디렉터리 안에 있는지 다시 한 번 확인해주세요. 디렉터리 구조가 정확해야 Flask가 템플릿을 찾을 수 있습니다.
Git 상태 확인 후 다시 푸시:
- templates/index.html이 Git에서 추적되고 있는지 확인하고, Heroku에 푸시하는 과정에서 파일이 누락되지 않도록 해야 합니다.
- 다음 명령어를 통해 templates/index.html을 Git에 추가하고 커밋한 뒤, Heroku에 다시 푸시해보세요.

git add templates/index.html templates/result.html
git commit -m "Add index.html and result.html to templates directory"
git push heroku master

템플릿 캐시 문제:

가끔 Heroku 배포에서 캐시 문제로 인해 파일 업데이트가 반영되지 않을 수 있습니다. 캐시를 무시하고 다시 배포하도록 아래 명령어를 사용할 수 있습니다.

git commit --allow-empty -m "Trigger Heroku redeploy"
git push heroku master

이 단계를 수행한 후 다시 Heroku 로그를 확인해보세요. 여전히 문제가 있다면 추가적인 로그를 공유해주시면 더 도와드릴 수 있습니다.
