Reclaim Space Server Error

pulpcore/app/viewsets/reclaim.py の25行目付近にある serializer の構築から始め、stack trace を確認しながら /pulp/api/v3/repositories/reclaim_space/ への POST リクエストを再現します。認証済みの POST で RepositoryVersionRelatedField の request-context assertion が発生しなくなり、成功または適切なプロセス開始レスポンスが返れば完了です。

AssertionError: `RepositoryVersionRelatedField` requires the request in the serializer context. Add `context={'request': request}` when instantiating the serializer.

To Reproduce
Go to /pulp/api/v3/repositories/reclaim_space/, login as admin and press POST

Expected behavior
I guess a message 200 or other kind of message that the process is started

Additional context
I think this line https://github.com/pulp/pulpcore/blob/main/pulpcore/app/viewsets/reclaim.py#L25 should add the context as described in the stack trace.

From:

serializer = ReclaimSpaceSerializer(data=request.data)

To:

serializer = ReclaimSpaceSerializer(
    data=request.data,
    context={'request': request},
)
