Make my admin web insert data to the firebase

This is the code the I used to send data from web using javascript to firebase but it doesn't work.

The authentication worked pretty well but other functions didn't work. I want to insert to the tours in the firebase new tour.

In the admin website there's a page called new tour that the admin going to fill the required info and then it goes to the firebase so basically the admin going to use this website to manage the firebase.
