Custom web build throws error


I’d like to use docker-jitsi-meet with a customized web service. I’ve cloned GitHub - jitsi/docker-jitsi-meet: Jitsi Meet on Docker. It works fine using the cloud image (jitsi/web:latest) but building a custom image (JITSI_RELEASE=unstable FORCE_REBUILD=1 JITSI_SERVICES=web make) results in a broken container. No error traces appear in the make command output. I run docker-compose up as normally, but the container crashes with the following information:

web_1      | exited 0.

Thanks in advance,
