@silavapi, what is the [status of this bug](https://github.com/mautic/mautic/issues/9557)?

With Mautic 4 and Composer 2, [Composer stalls](https://forum.mautic.org/t/getting-started-with-mautic-api/20669/13) on this same error with `composer require mautic/api-library --with-all-dependencies`, `composer update mautic/core --with-all-dependencies` and other commands:

> Your requirements could not be resolved to an installable set of packages.
> 
> Problem 1  
> - Root composer.json requires mautic/core-lib ^3.0 → satisfiable by mautic/core-lib[3.x-dev].  
> - mautic/core-lib 3.x-dev requires willdurand/oauth-server-bundle dev-release-0.0.3 → found willdurand/oauth-server-bundle[dev-master, 0.0.1] but it does not match the constraint.

The response to this bug (?) last February was:

> Please ensure that you are using Composer 1 - we will not be supporting Composer 2 until Mautic 4.

We’re now on Mautic 4 and Composer 2. Apparently willdurand/oauth-server-bundle 0.0.3 still does not exist - 0.0.1 does.

Why is willdurand/oauth-server-bundle required for Mautic 4 anyway? It is a ‘Server side implementation of the OAuth 1.0 protocol’ which is not included in Mautic 4 afaik.

What can I edit to skip this requirement and get past this error? I can’t find a mention of willdurand/oauth-server-bundle in the latest composer.json or anywhere in my Mautic installation.
