Correct path for firestore database in r - r

Question

Hi and thanks for reading me. I'm trying to connect to a database in firestore (firebase) following the steps of a tutorial I found on the internet, but I got a problem right now, and that is when trying to write the database path for the function , then it returns me an empty JSON. It does not give me any error message, so I assume that the connection to the firestore works, the problem arises when writing the path to the database.
The functions to connect to firestore are the following:
library(jsonlite)
library(httr)
sign.up <- function(email, password, api_key) {
#https://firebase.google.com/docs/reference/rest/auth/#section-create-email-password
r <- POST(paste0("https://identitytoolkit.googleapis.com/v1/accounts:signUp?key=", api_key),
add_headers("Content-Type" = "application/json"),
body = toJSON(list(email = email, password = password, returnSecureToken = TRUE),auto_unbox=TRUE))
return(content(r))
}
sign.in <- function(email, password, api_key) {
#https://firebase.google.com/docs/reference/rest/auth/#section-sign-in-email-password
r <- POST(paste0("https://identitytoolkit.googleapis.com/v1/accounts:signInWithPassword?key=", api_key),
add_headers("Content-Type" = "application/json"),
body = toJSON(list(email = email, password = password, returnSecureToken = TRUE),auto_unbox=TRUE))
return(content(r))
}
my_auth_info<-sign.in(
Sys.getenv("mail"),
Sys.getenv("password"),
Sys.getenv("token")
)
And the function to get the firestore data are the following:
read.db <- function(db_endpoint, auth_token) {
r <- GET(sprintf("https://firestore.googleapis.com/v1beta1/%s", db_endpoint),
add_headers("Content-Type" = "application/json",
"Authorization" = paste("Bearer", auth_token)))
return(r)
}
When i run the function with the following information I got an empty JSON:
read.db(
"projects/projectname/databases/(default)/documents/databasename",
my_auth_info$idToken
)
For the project name I use the following:
And for database name im using the following:
I need to use another information for the database path?
Thanks for the help
