Application error 발생하네요..

Question

첫번째 질문과 같은 내용인데 heroku에 서버 배포한 후 링크에 접속하면 application error라는 화면과 함께 heroku logs --tail라는 명령어를 사용해 에러내역을 확인할 수 있다는 설명이 나오는데요 명령어를 치면 아래와 같은 에러 로그가 나옵니다.. 2021-08-12T08:31:28.495603+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/product" host=cns-market-server.herokuapp.com request_id=bc225d89-0c68-47aa-8645-4f47a3070914 fwd="122.40.66.2" dyno= connect= service= status=503 bytes= protocol=https 2021-08-12T08:31:29.649909+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/products" host=cns-market-server.herokuapp.com request_id=cbad85c6-e6b3-4242-a56b-84193bf4e3e2 fwd="122.40.66.2" dyno= connect= service= status=503 bytes= protocol=https 2021-08-12T08:31:30.323147+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/favicon.ico" host=cns-market-server.herokuapp.com request_id=cfde8d99-32a8-4530-ae39-fafb1332f514 fwd="122.40.66.2" dyno= connect= service= status=503 bytes= protocol=https 2021-08-12T08:31:30.562650+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/favicon.ico" host=cns-market-server.herokuapp.com request_id=f0f93240-35af-4b36-96df-a1ae3d1b6f6e fwd="122.40.66.2" dyno= connect= service= status=503 bytes= protocol=https 2021-08-12T08:34:20.501997+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/" host=cns-market-server.herokuapp.com request_id=3ab3a4a2-7a21-4e39-96d9-37d90a558f38 fwd="122.40.66.2" dyno= connect= service= status=503 bytes= protocol=https 2021-08-12T08:34:20.739831+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/favicon.ico" host=cns-market-server.herokuapp.com request_id=06ed57ff-6c38-4ba2-88d6-7061096764d9 fwd="122.40.66.2" dyno= connect= service= status=503 bytes= protocol=https 2021-08-12T08:38:35.015107+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/" host=cns-market-server.herokuapp.com request_id=459f7523-24bb-4f04-b2f0-e19f69bf31ad fwd="122.40.66.2" dyno= connect= service= status=503 bytes= protocol=https 2021-08-12T08:38:35.241515+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/favicon.ico" host=cns-market-server.herokuapp.com request_id=980e9520-a501-4c68-b4dc-8d5b27efe7ff fwd="122.40.66.2" dyno= connect= service= status=503 bytes= protocol=https 2021-08-12T08:40:45.493362+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/" host=cns-market-server.herokuapp.com request_id=1bc17b4c-40aa-42d2-95a3-c3ffb17ee9ee fwd="122.40.66.2" dyno= connect= service= status=503 bytes= protocol=https 2021-08-12T08:40:45.754321+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/favicon.ico" host=cns-market-server.herokuapp.com request_id=6854ce8c-bf3c-4138-8321-990ab77b44bf fwd="122.40.66.2" dyno= connect= service= status=503 bytes= protocol=https 2021-08-12T08:40:59.354469+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/" host=cns-market-server.herokuapp.com request_id=de9e37c8-1575-4011-a531-4277660af310 fwd="122.40.66.2" dyno= connect= service= status=503 bytes= protocol=https 2021-08-12T08:40:59.603943+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/favicon.ico" host=cns-market-server.herokuapp.com request_id=b8418fdd-1287-4298-9a40-587671989bc7 fwd="122.40.66.2" dyno= connect= service= status=503 bytes= protocol=https 2021-08-12T08:49:40.640664+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/" host=cns-market-server.herokuapp.com request_id=02803cf7-06b0-4c8d-8cd6-04c426848614 fwd="122.40.66.2" dyno= connect= service= status=503 bytes= protocol=https 2021-08-12T08:49:40.857902+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/favicon.ico" host=cns-market-server.herokuapp.com request_id=30fae789-9ef9-4975-bbd0-5e9894f9910f fwd="122.40.66.2" dyno= connect= service= status=503 bytes= protocol=https 2021-08-12T08:52:50.646041+00:00 heroku[web.1]: State changed from crashed to starting git heroku push 할 때는 특별한 log 보이지 않았고 Local로 동작시 이상없이 동작합니다.. 검토 부탁 드립니다.

웹이 제대로 동작하지 않거나, 부팅 시간이 오래걸렸을 때 생기는 이슈인 것 같아요! 아래 소스코드와 동일하게 구성하셨을까요? https://github.com/yansfil/grab-market-server/commit/e431431c21f547e395cb3e294fdc40e315b35464
