I have followed all steps of DEVELOPERS.md even though I keep getting this error

These are the steps I followed are:

1.Installed Docker Desktop

2.Created a .env file in the root of the MediaWiki core repository, and copied these contents into that file:

MW_SCRIPT_PATH=/w
MW_SERVER=http://localhost:8080
MW_DOCKER_PORT=8080
MEDIAWIKI_USER=Admin
MEDIAWIKI_PASSWORD=dockerpass
XDEBUG_CONFIG=
XDEBUG_ENABLE=true
XHPROF_ENABLE=true

3.Started the container:

docker compose up -d

4.Installed PHP dependencies from Composer:

docker compose exec mediawiki composer update

5.Installed MediaWiki:

docker compose exec mediawiki /bin/bash /docker/install.sh

The following is the output I got after running the last command:
