const Event = mongoose.model('Event',eventSchema,'events');
module.exports = Event;

const User = mongoose.model('User',userSchema,'users');

any help would be appreciated 

Answer 1

This is mongoose Error mostly due to mongoose connection not finding URL for POST or GET API.

1. One other chance is to make sure you have created a /data folder inside your mongoose installation location with bin and start mongoose service which is Mongoose and mongod.exe and try with Mongodb compass for checking connection is successful or not.

2. other like check your Mongo connection is connected properly if it is connected or not in DB connection URL.

Answer 2

You are trying to get userId from req.user_id.

it must from req.body.user_id like this:

 user_id:req.body.user_id,
