Error trying to use custom certificates

[SimonHenz97]

Hello, my Team needs to serve jsReport via https (no we are not allowed to use a reverse proxy...)
so in order to test https I created a test certificate and supplied them using docker-compose

    ports:
      - ${PORT}:443
    volumes:
      - jsreport:/jsreport
      - certs:/certs
    environment:
      httpsPort: 443
      certificate.key: certs/${SSL_KEY}
      certificate.cert: certs/${SSL_CERT}

the certifcates are available in the right directory in the container but if I try to run it I get this error

I checked multiple times, there are no typos in the filenames etc.

Any help is appreciated, thx!

Ok, I managed to find a solution

    ports:
      - ${PORT}:443
    volumes:
      - jsreport:/jsreport
      - certs:/certs
    environment:
      httpsPort: 443
      certificate_key: /certs/${SSL_KEY}
      certificate_cert: /certs/${SSL_CERT}

I needed to specify the certs directory from the root...
And the config path needed a ' _ ' not a ' . ' , I don't know how I made that assumption
