CommandSubscriber not found after upgrading symfony version 3.4 to 6.2

Question

I have upgrade symfony version from 3.4 to 6.2 and mostly it's working but after attaching MongoDB I'm getting this error.

Class "MongoDB\Driver\Monitoring\CommandSubscriber" not found while loading "Doctrine\Bundle\MongoDBBundle\APM\StopwatchCommandLogger".

Here is the visual of the error

Where I am making mistakes ? Much thanks in advance.

here is my composer.json content

I did 3 to 4 hours googling but couldn't find any solution so I thought I should post it on stack overflow so I can get answers from the community.

Answer 1

Are you trying to do a composer install with '--ignore-platform-reqs' flag? My assumption is that the package 'doctrine/mongodb-odm' is skipped because you do not have installed and enabled the 'ext-mongodb' php extension.

Could you try running the composer install without '--ignore-platform-reqs' flag?
