Provided examples won't start

I am using 7a4e3153d682c33e92740b6e0b24e1dc9e6bc6b6 and trying to spin up simple text classifier. The docker compose works OK, but I can't connect to http://localhost:9090/health.
```
>docker compose up
[+] Running 2/0
- Container redis Running 0.0s
- Container server Created 0.0s
Attaching to redis, server
server | => LABEL STUDIO HOSTNAME = http://localhost:8082
```
Nothing happens if I open `http://localhost:9090/health` or `http://localhost:9090`.

Version 1.0.3 and commit a1dc0bc runs (however gives `internal server error`).

Start by reproducing the reported command with commit 7a4e3153d682c33e92740b6e0b24e1dc9e6bc6b6 and inspect the example's Docker Compose configuration and service logs. Compare its behavior with version 1.0.3 and commit a1dc0bc, then verify that the documented health endpoint responds successfully when the issue is fixed.
