      Problem Statement/Rationale

      Aggregation stage ...

      $limit stage
      {$limit: 9223372036854775807}

      ... doesn't work - there is an error reported.

      $limit stage
      {$limit: 9223372036854775295}

      ... seems to be the maximum number that does not produce an error, although, I'm not confident that number is actually sent to the server.  I observed port 27017 packets with wireshark and noted unusual 64-bit numbers being sent to the server for the $limit value.  Packets sent by pymongo looked normal and expected.

      Steps to Reproduce

      Enter $limit stage as above and observe error.

      Expected Results

      Accept 2^63-1 as valid $limit value

      Actual Results

      Error message

      Additional Notes

      This bug also applies to mongosh, the mongosh in compass, and MongoDB Atlas aggregation.

      This bug does NOT appear in pymongo.
