How To Solve MongoParseError: options useCreateIndex useFindAndModify are not supported Error ?

Solution 1: Remove options

Here in Mongoose 6.0 useNewUrlParser, useUnifiedTopology, useFindAndModify, and useCreateIndex are no longer supported options. So that just remove that option. and again try to connect as same like below.

Mongoose.connect(
    MONGODB_URL,
    async(err)=>{
        if(err) throw err;
        console.log("conncted to db")
    }
)

Solution 2: Downgrade to below 6.0
