Hello everyone, im new to MongoDb and actually im new to the developer world so my apoligies if this question sound silly but im developing my first full stack project with Reactjs, Nodejs and Mongo. Im trying to send a form data into my database collection named “ecommerce” but every data i send from the client side are store in a folder named “Test” i didnt even create.
