sourcify: Fail to run Sourcify from Docker containers

I am trying to run locally from containers.

• cloned the repo
• created environments/.env from environments/.env.dev
• made these changes in .env:

# Server config
REPOSITORY_PATH=/Users/svienot/GIT/ethereum/sourcify/repository
SOLC_REPO=/Users/svienot/GIT/ethereum/sourcify/solc-bin/linux-amd64
SOLJSON_REPO=/Users/svienot/GIT/ethereum/sourcify/solc-bin/soljson
…
# Docker config
## Where to mount the downloaded compilers directory on the host machine
SOLC_REPO_HOST=/Users/svienot/GIT/ethereum/sourcify/solc-bin/linux-amd64
SOLJSON_REPO_HOST=/Users/svienot/GIT/ethereum/sourcify/solc-bin/soljson
…
SERVER_URL=http://localhost

• ran this: $ docker-compose -f repository.yaml -f server.yaml -f ui.yaml up -d

Services start fine, nothing too suspicious in the logs, but when I try to use the Verifier, I get the following error:
