MongoDB - Error: invalid schema, expected mongodb

Question

I\'m new in building application with MEAN Stack, I\'m trying to build a real time chat app, here is my server side :

console.log(\"Server running...!\");

v         


        

Answer 1

I just had this issue as well and it was because I had the protocol wrong:

mongo://localhost:27017/test

The protocol being wrong can also cause this error. It should be like this:

mongodb://localhost:27017/test
