Current Behavior

I wrote a query involving $accumulator and ran it in robo 3t as well as Mongo DB Compass

In Robo 3t when I run Query it says that "ok" : 0, "errmsg" : "unknown group operator '$accumulator'", "code" : 15952, "codeName" : "Location15952" robo3t error

Even in Mongo Db Compass

unknown group operator '$accumulator' mongoCompass

Which mongodb server version are you using? $accumulator is a new feature in 4.4, and the error message is what you would get if you ran it against a server with a lower version.
