Docker FastAPI Deploy Error: Health Checks, but I have /health route

I try to set up CD for my fastapi app using digital ocean app and digital ocean private container registry

My desired pipeline:

1. Build docker with github actions when github receives a push to main branch
2. Push docker to digital ocean private container registry
3. Digital ocean app run deployment with new docker

I stuck at step 3, because I always get Deploy Error: Health Checks.
My Health check settings at digital ocean.
When I run my app locally

• Health docs
• / docs

How I run my fastapi app:

poetry run uvicorn supa_dupa_api.main:app --port 8080 --host '::' --workers 1

Digital Ocean build logs:

Skipping virtualenv creation, as specified in config file.
INFO:     Started server process [3]
INFO:     Waiting for application startup.
INFO:     Application startup complete.
INFO:     Uvicorn running on http://[::]:8080 (Press CTRL+C to quit)

Please help me. How I can avoid this error? the service is working, but crashes after a few minutes due to this error

Additional information:

• I tried default settings for health checks
• I tried a different port
