unexpected EOF when trying to fetch from remote

Commands.Fetch と FetchOptions から開始し、fetch リクエストが multi_ack_detailed、side-band-64k、include-tag などの機能をどのように通知するかを追跡します。これを動作する OS Git のリクエストと比較し、LibGit2Sharp がこれらのオプションを制御する手段を公開しているか判断します。対応する構成、または Bitbucket 7.21.4 との再現可能なプロトコル非互換性を特定できれば完了です。

I'm having an issue with a remote repo hosted on a BitBucket v7.21.4. The clone command works just fine, but when I try to fetch a particular branch if fails with LibGit2Sharp.LibGit2SharpException: unexpected EOF.
The issue is constantly reproducible.

Reproduction steps

Example code:

        using var repo = new Repository(repositoryPath);
        var fetchOpts = new FetchOptions();
        fetchOpts.CertificateCheck = (_,_,_) => true;
        fetchOpts.CredentialsProvider = (_, _, _) => new UsernamePasswordCredentials() { Username = remoteUser, Password = remotePassword };
        fetchOpts.Prune = true;
        fetchOpts.TagFetchMode = TagFetchMode.None;
        var remote = repo.Network.Remotes["origin"];
        Commands.Fetch(repo, remote.Name, [$"+refs/heads/{remoteBranch}:refs/remotes/{remote.Name}/{remoteBranch}"], fetchOpts, null);

Expected behavior

Fetch to complete successfully.

Actual behavior

Unhandled exception. LibGit2Sharp.LibGit2SharpException: unexpected EOF

Below is the trace:

Below is the the trace from the OS git client fetch from the same remote which works just fine:

I noticed that it sends only thin-pack and ofs-delta arguments as opposed to multi_ack_detailed side-band-64k include-tag thin-pack ofs-delta from libgit2sharp.
Is there a way to control this behavior with code?
