Kindly note that, the "$collStats" Stage Operator is not supported in any DocumentDB version currently. This is also mentioned in the document below[1].
Having said that, currently there is no alternative for passing aggregated functions or combining outputs of two stages in aggregate query in DocDB. Please be aware, you will have to use separate queries and re-structure the same to mitigate this issue.
Going forward, you can keep an eye on AWS announcements [2], as all new releases in DocumentDB would be posted here.

Hi Ruchi, Issue is I am not able to do mongodump or mongoexport as per the guide I have linked in the question. I am not trying to use the $collStats operator, rather mongodump/mongoexport is throwing the said error.
