I have not personally run into this, but I did some digging around online for you and found the following page on Stack Overflow:

MongoError: Transaction numbers are only allowed on a replica set member or mongos

The gist of the article starts that you need a Mongo replica set, and it gives instructions on how to accomplish this.

I hope this is helpful - please let me know if this works for you!
