[Question] App crashes, where can I find the nginx log files for that specific app ?

Hello all !
I have a running NestJS (Nodejs + Typescript) API. It works well but one specific endpoint (/auth/signup).
Here is the App logs Caprover gives me :

We can see that the app restarts automatically and silently. I don't know what is the problem.. I tried to debug with my localhost setup and all works just fine, I think it's maybe because of NGINX.
Where can I find the NGINX detailed logs ???

Thx a lot :)

You can get nginx logs via

docker service logs captain-nginx --since 10m

and you can get your own apps logs from

docker service logs srv-captain--yourappname --since 10m

The commands above only return the last 10 minutes. Feel free to change the time span.
