title: migrating to git lfs by official guide creates bad object error
body: <p>Following <a href="https://docs.gitlab.com/ee/topics/git/lfs/migrate_to_git_lfs.html" rel="nofollow noreferrer">this guide</a>, when I get to the step <code>git push --force</code> I get the following error:</p>
  <pre class="lang-sh prettyprint-override"><code>ref master:: Error in git rev-list --stdin --objects --not --remotes=origin --: exit status 128 fatal: bad object d096dd7506987ff3ede8754716b5fe076836b524
  error: failed to push some refs to &lt;git-url&gt;
  </code></pre>
  <p>I have followed the guide exactly so am at a loss. Any suggestions welcome.</p>
  <p>TIA</p>
