[SOLVED] Api-platform 2.7 - Unable to generate an IRI for the item of type

I'm facing a problem using Api-platform:2.7. Everything works fine in my application with PHP Attributes and APi resources. However, I find out that when I composer require doctrine/mongodb-odm-bundle, all the POST resources become unusable. my application is using both an SQL and a Mongo database.

Removing the composer package fix the error.

This is the doctrine_mongodb.yaml I'm using (I tried with and without the auto_mapping. Same error)

doctrine_mongodb:
    auto_generate_proxy_classes: true
    auto_generate_hydrator_classes: true
    connections:
        default:
            server: '%env(resolve:MONGODB_URL)%'
            options: {}
    default_database: '%env(resolve:MONGODB_DB)%'
    document_managers:
        default:
            # auto_mapping: true
            mappings:
                App:
                    is_bundle: false
                    type: attribute
                    dir: '%kernel.project_dir%/src/Document'
                    prefix: 'App\Document'
                    alias: App

Here is the error stacktrace:
