Docker Compose v2.34.0 Issue with -e Flags

[quique0194]

Today I updated my debian, and had a problem with docker compose version (v2.34.0)

I have fab as an alias of: docker compose run -it --rm -e MONGO_WRITE_USER="$MONGO_WRITE_USER" -e MONGO_WRITE_PWD="$MONGO_WRITE_PWD" -e DOCKER_HOST_USER="$USER" dc-fab fab "$@"

When running the following command:

fab download-col apurata pos_client

I was getting the error pasted below. But when removing the "-e" flags, it worked. It was broken even with -e MYVAR="hello"
Then I installed the previous version of docker (v2.33.1) and it worked again.

~/apurata/webserver master ⇡1 ❯ fab download-col apurata pos_client
panic: assignment to entry in nil map

I don't think you'll need it, but here is my definition of dc-fab:

  dc-fab:
    profiles: [manually-launched]
    build:
      context: ./webserver
      dockerfile: Dockerfile-fab
    volumes:
      - ./webserver:/workdir
      # We copy ~/.ssh to allow fabric commands to work, e.g. fab download-docs ...
      - ~/.ssh:/root/.ssh
    env_file:
      - ~/.apurata/.env_personal  # e.g. mongo_pwd to use with fabric
    working_dir: /workdir  # workdir is used when running mongo-client
