docs: <p>
  A list containing one object for each document that contained an error. The results are sorted in ascending order
  by the <code>Index</code> field and match the order of the documents in the input list. If there are no errors in
  the batch, the <code>ErrorList</code> is empty.

  <b>NOTE:</b> This method appends the values to the existing list (if any). Use
  {@link #setErrorList(java.util.Collection)} or {@link #withErrorList(java.util.Collection)} if you want to
  override the existing values.
