Failed push not displaying pre-receive hook error message

[pablonardone]

Executing a push that is rejected by the pre-receive hook on the server side, the OnPushStatusError notification is not displaying the error message returning by the remote git server, it is just showing the generic error pre-receive hook declined.

Executing the same push but with the git command line, the message error is dsplayed correctly.

 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'https://nsgitlab/pablo.nardone/test3.git'

Reproduction steps

Setup a pre-receive hook that reject the push with some specific error message. In my case the message is GL-HOOK-ERR: MY SPECIFIC ERROR MESSAGE. Execute from command line git push origin master and verifiy the push si rejected and the specific error message is displayed correctly. Execute the same push operation but this time with the LibGit2Sharp library and verify the push is rejected but only displaying the generic error pre-receive hook declined and not the specific error returning by the pre-receive hook.

try
{
	PushOptions options = new PushOptions
	{
		OnPushStatusError = (PushStatusError pushStatusErrors) =>
		{
			throw new Exception($"OnPushStatusError - Reference({pushStatusErrors.Reference}) Message({pushStatusErrors.Message})");
		},
	};
	repo.Network.Push(branch, options);
}
catch (Exception ex)
{
	Debug.WriteLine(ex.Message);
}

Expected behavior

OnPushStatusError - Reference(refs/heads/master) Message(pre-receive hook declined. GL-HOOK-ERR: MY SPECIFIC ERROR MESSAGE)

Actual behavior

OnPushStatusError - Reference(refs/heads/master) Message(pre-receive hook declined)

@pablonardone , Is there anyway to get hook name / or full error message.
