Dependency on a non-existent service "doctrine.orm.metadata.annotation_reader"

Question

So I have a Symfony 6.2 API, PHP 8.2 codebase.

While trying to run composer install/update the following error is displaying and I'm wondering how to clear it:

In CheckExceptionOnInvalidReferenceBehaviorPass.php line 83:
The service "doctrine.orm.default_annotation_metadata_driver" has a dependency 
on a non-existent service "doctrine.orm.metadata.annotation_reader".

If I comment out the mappings section in doctrine.yaml file (below) composer runs successfully, however all POST requests to the api will then result in the following error:

Could not find the entity manager for class App\Entity\Token.
Check your Doctrine configuration to make sure it is configured 
to load this entity’s metadata. (500 Internal Server Error)

Scratching my head here to understand how to resolve it. I've a feeling it may be doctrine.yaml related but I could be miles off the mark.

composer.json:

"require": {
        "php": ">=8.2",
        ...
        "doctrine/doctrine-bundle": "^2.8",
        "doctrine/doctrine-migrations-bundle": "^3.2",
        "doctrine/orm": "^2.14",
        ...
    },

doctrine.yaml:

doctrine:
    dbal:
        url: '%env(resolve:DATABASE_URL)%'

    orm:
        auto_generate_proxy_classes: true
        naming_strategy: doctrine.orm.naming_strategy.underscore_number_aware
        auto_mapping: true
        mappings:
            App:
                is_bundle: false
                dir: '%kernel.project_dir%/src/Entity'
                prefix: 'App\Entity'

You are missing the doctrine/annotationsdependency. Try to add in your composer.json file:

"doctrine/annotations": "^1.0",

Then run composer update. Or just run:

composer require doctrine/annotations
