Cannot install new extension from marketplace using latest docker image

[xcellenceit]

With the latest docker image I am running, I am getting following error when trying to install extension from marketplace. And due to that I cannot install any extension from MarketPlace.

Heads up! Composer is required for installing and updating plugins in the Marketplace. It looks like you're not using Composer yet, so you'll only be able to browse the Marketplace. Want to switch to Composer today?

You can check the screenshot here

Note that, the dropdown beside extension is also blank! I am not sure if this is correct behaiour as I am trying mautic for the first time.

Here is the docker-compose I am using for this...

`version: "2"

services:
database:
image: powertic/percona-docker
container_name: database
environment:
MYSQL_ROOT_PASSWORD: mypassword
ports:
- "3306:3306"
volumes:
- database:/var/lib/mysql
restart: always
networks:
- mauticnet
command: --character-set-server=utf8mb4 --collation-server=utf8mb4_general_ci --sql-mode=""

mautic:
container_name: mautic
image: mautic/mautic:v4-apache
volumes:
- mautic_data:/var/www/html
environment:
- MAUTIC_DB_HOST=database
- MAUTIC_DB_USER=root
- MAUTIC_DB_PASSWORD=mypassword
- MAUTIC_DB_NAME=mautic4
restart: always
networks:
- mauticnet
ports:
- "8880:80"

networks:
mauticnet:

volumes:
database:
mautic_data:`

Pls guide what could be wrong and how to fix this.

What version of Mautic did it install? I noticed it isn't installing the latest 3.2.4 version

I am meeting this issue with Mautic 5 via the example or the fpm install

I am using docker image for mautic from mautic/mautic:v4-apache
