Chirpstack container exit code 0 when copying clang-wrapper from cache.nixos.org (docker compose with v4.7.0)

Hi there,

I want to start development with chirpstack and have done the following:

...
chirpstack-1     | copying path '/nix/store/cb4mxc1mnl97590zbbhclgvqn4iqqap7-gcc-wrapper-12.3.0' from 'https://cache.nixos.org'...
chirpstack-1     | copying path '/nix/store/nkskw6n4swnlxjrwv47mpb4a4h8r85wg-stdenv-linux' from 'https://cache.nixos.org'...
chirpstack-1     | copying path '/nix/store/hyig8wi4j2xkf2l3zwsws2hdkz86wgbn-clang-16.0.6-lib' from 'https://cache.nixos.org'...
chirpstack-1     | copying path '/nix/store/v2dpa13x6c6g50cksd0gbx3k8v9y8d2r-clang-16.0.6' from 'https://cache.nixos.org'...
chirpstack-1     | copying path '/nix/store/a7c59h5m06b7q47l33f49b5216l4lw52-clang-wrapper-16.0.6' from 'https://cache.nixos.org'...
chirpstack-1 exited with code 0

Can You give me a hint where to start debugging this?

A sidenote: To make the UI Container work, I had to get rid of the RUN apk line (as node and so on is already included in the image…)

Any help appreciated!
