Failed to initialize a MongoDB replica set.

While starting my fresh project using reaction develop . It is not starting instead showing error

Failed to initialize a MongoDB replica set. This may result in errors or some things not working. Error: Error checking replica set config: not running with --replSet (NoReplicationEnabled)

MongoError: The $changeStream stage is only supported on replica sets at MessageStream.messageHandler (/home/dev/Desktop/Office/demo projects/Reaction Ecommerce/project1/server/node_modules/mongodb/lib/cmap/connection.js:268:20) at MessageStream.emit (events.js:400:28) at MessageStream.emit (domain.js:475:12) at processIncomingData (/home/dev/Desktop/Office/demo projects/Reaction Ecommerce/project1/server/node_modules/mongodb/lib/cmap/message_stream.js:144:12) at MessageStream._write (/home/dev/Desktop/Office/demo projects/Reaction Ecommerce/project1/server/node_modules/mongodb/lib/cmap/message_stream.js:42:5) at writeOrBuffer (internal/streams/writable.js:358:12) at MessageStream.Writable.write (internal/streams/writable.js:303:10) at Socket.ondata (internal/streams/readable.js:731:22) at Socket.emit (events.js:400:28) at Socket.emit (domain.js:475:12) { ok: 0, code: 40573, codeName: 'Location40573' }
Is there anyone got issue?

I think you have already running your mongodb server without the replica set config.
I have encoutered the same probleme because I already have mongodb installed on my system (without replica set) , and the app will always use that, so my solution was to stop it first before running reaction api.
