Solution

1. Go to vendor/sonata-project/doctrine-mongodb-admin-bundle/src/Exporter/DataSource.php
2. Interface SourceIteratorInterface used on return function of createIterator not exist, replace by DoctrineODMQuerySourceIterator work, but it's fine ?

The issue is that sonata-project/exporter": "^2.0 was not in the dependencies so you're installing 3.0 in which the class was removed.

I'll do a fix. But you can require sonata-project/exporter": "^2.0" to fix your issue temporary.
