Docker build fails

[WolfCabo]

The docker build fails on the client build part (client/Dockerfile).

COPY client/yarn.lock .
COPY failed: file not found in build context or excluded by .dockerignore: stat client/yarn.lock: file does not exist

After checking there's indeed no yarn.lock file present in the client folder.
No idea if it's needed or not, could you please add the file or remove the copy line from the Dockerfile?

Thanks!

I've retried it by commenting out the copy client/yarn.lock .
Build works, but seeing quite a bit of messages about outdated packages.

The server container fails to start though:
yarn run v1.22.15,
error Command "start-prod" not found.,
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.,

I can't find anything on start-prod in the package.json though. Not sure how to proceed on this.
