Mongo connection error

[PrettiestRobot]

I kept receiving a notification whenever I would run nodemon telling me there was a vulnerability and suggesting I run an audit. I did and it said I should update mongoose to a new version. Ever since the update I'm getting this error and I can't start the server:

I fixed it. After a quick search on stack overflow, I needed to remove:

usecreateindex
usefindandmodify

from my mongoos.connect function.
