nodegit avoid creating empty commit nodejs bitbucket

Question

I am using following code to create a commit using nodegit library of nodejs

function createCommit(commitMsg) {
  console.log("Creating commit");
  let repository, index, oid, author, committer;
  return NodeGit.Repository.open(bb.repoPath)
    .then(function (repo) {
      repository = repo;
      return repository.refreshIndex();
    })
    .then(function (idx) {
      index = idx;
      const entryCount = index.entryCount();
      console.log("file: nodegit.js:74 ~ entryCount:", entryCount);
      if (entryCount === 0) {
        console.log("No changes to commit.");
        return;
      }
      return index.addAll();
    })
    .then(function () {
      return index.write();
    })
    .then(function () {
      return index.writeTree();
    })
    .then(async function (oidResult) {
      const head = await NodeGit.Reference.nameToId(repository, "HEAD"); // get reference to the current state
      const parent = await repository.getCommit(head); // get the commit for current state
      oid = oidResult;
      author = NodeGit.Signature.now(bb.name, bb.email);
      committer = NodeGit.Signature.now(bb.name, bb.email);
      return repository.createCommit("HEAD", author, committer, commitMsg, oid, [parent]);
    })
    .then(function (info) {
      console.log("Commit created successfully!");
      return info;
    })
    .catch((err) => {
      console.log("Error creating commit:", err);
      throw err;
    });
}

I am checking the entryCount as well

      const entryCount = index.entryCount();
      console.log("file: nodegit.js:74 ~ entryCount:", entryCount);
      if (entryCount === 0) {
        console.log("No changes to commit.");
        return;
      }

but even if there is no file to commit it shows >0 entryCount.

I tried

git reset --hard

still there is entry count and makes an empty commit.

What can be the issue? is there any other solution?

By checking the number of files to commit we can avoid empty commits

function getChangesCount() {
  return NodeGit.Repository.open(bb.repoPath)
    .then(repository => {
      return repository.getStatus();
    })
    .then(statuses => {
      return statuses.length;
    }).catch(error => {
      console.error(error);
      return null;
    });
}
