**API Platform version(s) affected**: 3.0.10 <!-- Warning: if your version is 2.7 we ask you to try the 3.0 version. If the bug is present there we will fix it. If the bug is due to old 2.6 behavior we can't fix it. In that last case we recommend to either upgrade to 3.0 or to temporarily replace concerned service with your own. --> **Description** Unable to use the provided Dockerfile to build `caddy` service. During the `caddy` image build (builder), an error occurs and seems to be linked to the latest stable version of caddy. `crypto/ecdh: Package crypto/ecdh is not in GOROOT` **How to reproduce** Just get the 3.0.10 release of API-Platform and `docker compose build`. **Possible Solution** As a workaround, I just used the `2.7-builder-alpine` tag for `caddy` build and `2.7-alpine` for `caddy` runner.
