cannot execute git fetch

[xavgru12]

Reproduction steps

I have a git repository with remote origin.

repository = new Repository(repositoryRootPath);
var remote = repository.Network.Remotes["origin"];
IEnumerable refSpecs = remote.FetchRefSpecs.Select(x => x.Specification).ToList();
Commands.Fetch(repository, remote.Name, refSpecs, new FetchOptions(), "ok");

Expected behavior

I expect it to run through.

Actual behavior

error:
NativeMethods.git_remote_fetch(remote, ref array.Array, fetchOptions, logMessage);
returns non zero
