same with composer auto-scripts

composer.json used: https://pastebin.com/JtHk3ZiV

strange because calling symfony console cache:clear gives no errors The only not usual thing I'm using is the composer via docker this way:

#!/bin/sh

docker run --rm --interactive --tty \
    --user "$(id -u)":"$(id -g)" \
    --volume "$(pwd)":/app \
    --volume "${COMPOSER_HOME:-$HOME/.composer}":/tmp \
    --workdir /app \
    --env COMPOSER_HOME=/tmp \
    composer "$@"

OK it seems the issue is from using the composer's docker image. When using for example composer.phar inside a container with PHP the problem is gone.

I have a similar issue with monolog, I tried as you mentioned to download composer.phar and use it inside the container but the same issue persists.
