updateSubmodulesRecursevly.js

function updateSubmodulesRecursevly(repository, cloneOptions) {
  return repository.getSubmoduleNames().then(function(names) {
    return names.reduce(function(promiseChain, name) {
      return promiseChain.then(function() {
        return new Promise(function(resolve, reject) {
            Submodule.lookup(repository, name)
              .then(function(submodule) {
                return submodule.init(1)
                  .then(function(result) {
                    return submodule.update(1, cloneOptions)
                  })
                  .then(function() {
                    let submoduleRepoPath = path.join(repository.workdir(), submodule.path());
                    return Repository.open(submoduleRepoPath)
                      .then(function(submoduleRepository) {
                        return updateSubmodulesRecursevly(submoduleRepository, cloneOptions);
                      })
                  })
                  .then(resolve, reject)
            });
        });
      });
    }, Promise.resolve());
  })
}

I get the following error on the call to submodule.update: 'protos' exists and is not an empty directory. However, if I cd into the parent directory and run git submodule update it executes without any problems. Any chance you know what might be going on?
