MongoDB & Symfony 6: Doctrine/mongodb-orm could not installed (Docker) - mongodb

Question

I'm trying to connect my Symfony 6 project with the MongoDB database on the Docker environment but when I launch the following command
composer require doctrine/mongodb-odm
This message appears
Your requirements could not be resolved to an installable set of packages.
Problem 1
- doctrine/mongodb-odm[1.0.0, ..., 1.0.8] require symfony/console ~2.3|~3.0 -> found symfony/console[v2.3.0, ..., v2.8.52, v3.0.0, ..., v3.4.47] but it conflicts with your root composer.json require (6.1.*).
- doctrine/mongodb-odm[1.1.0, ..., 1.3.7] require php ^5.6 || ^7.0 -> your php version (8.1.12) does not satisfy that requirement.
- Root composer.json requires doctrine/mongodb-odm ^1.0 -> satisfiable by doctrine/mongodb-odm[1.0.0, ..., 1.3.7].
You can also try re-running composer require with an explicit version constraint, e.g. "composer require doctrine/mongodb-odm:*" to figure out if any version is installable, or "composer require doctrine/mongodb-odm:^2.1" if you know which you need.
Installation failed, reverting ./composer.json and ./composer.lock to their original content.

Is there any point that I did not notice in the above files, and is there any solution to the following problem?

Answer 1

If you want to use PHP 8.1, upgrade mongodb-odm to version 2.3. This is the first version to support PHP 8 as outlined in this statement:
We have released a new minor version 2.3 of Doctrine MongoDB ODM, the first version with support for using PHP 8 Attributes as a new driver for mapping documents and several other changes. See all changes and contributors in the Changelog on GitHub.
Otherwise, downgrade to PHP 7.0 as indicated in the error message.
